Euristic analysis. Preparing for military training

Heuristic analysis (Heuristic scan)- the supremacy of the anti-virus functions, aimed at detecting non-homemade databases of high-profile programs. In the same hour, the term means one of specific methods.

Practically all modern anti-virus technologies use the technology heuristic analysis program code. Heuristic analysis is not easy to pick up on signature scans for the joke of folding ciphers and polymorphic viruses. The method of heuristic analysis permits the appearance of infectious diseases before, however, in such cases it is practically impossible to detect in such cases. In such a case, as a rule, additional updates of anti-virus databases are not required to deny the remaining signatures and algorithms for the search, as it is possible to revenge information about the earlier unavailable viruses. In the іnshomu vipadku, the file is transferred for further review by anti-virus analysts or the authors of anti-virus programs.

Heuristic analysis technology

The method of Heuristic scanning does not neglect the guaranteed acquisition of all new ones, which are included in the signature set of computer viruses, which is explained to the victors in the capacity of analyzing signatures earlier than in the rules of the European viruses. At the same hour, the odd method of joking is based on empirical prizes, but it is not possible to win prizes.

In a number of types of Heuristic methods, they appear to be superbly successful, for example, even in the time of short program parts in the enchanting sector: if the program is to write to sector 1, road 0, side 0, then it is necessary to accumulate until the change of distribution. Along with the additional programs of fdisk, the team is no longer vicky, and in the case of an unsupported message, show me about the inviting virus.

In the process of heuristic analysis, the code emulated by the analyzer is carried out. For example, the program is informed by a polymorphic virus, which is stored in an encrypted file and a decryptor. The simulator reads the instructions into the antivirus buffer, picks them up on the instructions and checks them out according to the same instructions, when the analyzer sends the code to the anti-virus buffer, it starts running. The emulation is trivial to quiet feast, as long as it is necessary for the control of the control sumy, the part of the virus will be deciphered. Yaksho signature has been signed - the program has been marked.

Incomplete Heuristic Scanning

• The overwhelming suspicion of a heuristic analyzer can be cleared of help if fragments of code are visible in the program, such as the status of the message and / or the last, including the authorities in the case of certain viruses. Zokrema, an unpacker in files packed with a PE-packer (Win) Upack wikiwand messages for a number of anti-virus problems, as there are no such problems.

• Revealing simple techniques to deceive the heuristic analyzer. As a rule, the first time to expand the widespread program (virus), the dealers continue to see the new expansion of the anti-virus products, using different methods of unique detection in the case of the heuristic scan. For example, code, vikoristovuyuchi elements, vikonannya which are not subject to the emulator code of given anti-viruses, vikorystovyuchi encrypted parts of the code and in.
• Unimportant on the announcements and advertisements of the development of anti-virus mechanisms, the effectiveness of the Heuristic scan is far from the point of view.
• It is practical to navigate with a successful result, to find an unheard-of virus. Yak vinyatok, in some products can be found in the same type and in a number of polymorphic ones, the code of viruses, since they do not conceal the permanent, varied til, but rather vikoristovuyu to use one technique in vvadzhennya. In such a way, for dozens and hundreds of viruses, there can be one entry in the virus base.

Anti-Virus Zahist.

The main way to fight bully viruses is to use anti-virus programs. You can vikoristovuvati anti-virus programs (anti-viruses), do not be aware of those like the stink of the virus. However, without the reasonable principles of organizing anti-viruses, knowing the types of viruses, as well as the methods of their expansion, it is impossible to organize a reliable computer hijacker. As a result, the computer can be infected, if antivirus is installed on the new one.

A few of the fundamental methods of revealing that to the origin of the viruses:

· Scanuvannya;

· Euristic analysis;

· Vikoristannya anti-virus monitors;

· Viyavlennya zmin;

· Vikoristannya anti-virus, installed in the BIOS of the computer.

In addition, practically all anti-virus programs will automatically update infected programs and entangled sectors. Squeaky and pricey.

The simplest technique is that the anti-virus program looks at the files after the first glances into the joke of the signatures of the viruses. Given the signature, the unique nature of the electronic data should be recognized, so that the virus can be detected, and not be used in other programs.

Anti-virus scanners let you know only if there are any viruses, for which a signature is assigned. Zasosuvannya simple program-scanners does not hijack Your computer from the penetration of new viruses.

In order to encrypt polymorphic viruses that have changed their code when they are infected with new programs, or the enchanting sector, it is hard to see the signature. Because of this, anti-virus scanners cannot detect polymorphic viruses.

Heuristic analysis allows to detect earlier unavailable viruses, moreover, it is not necessary to collect data about the file system in advance, which is, for example, looking at the lower method of detecting changes.

Anti-virus programs that implement the method of heuristic analysis, rewrite the programs and enchant sectors of disks and floppy disks, add the code characteristic of viruses to them. The heuristic analyzer can be used, for example, when the program is being revised, it will install the resident module in the memory, or write down the data in the created program file.

Practically all modern anti-virus programs implement the most powerful methods of heuristic analysis. In fig. 1 we showed one of these programs - a McAffee VirusScan scanner, launched manually for anti-virus disk rewiring.

If the antivirus detects infections in the file, let it be added to the monitor screen and to prevent the entry from the system log. Regardlessly, the anti-virus can also be used to direct any manifestations of the virus of the fenestration administrator.

As well as possible, anti-virus file, new version. Only one possibility is displayed in the last vipad - to see the infection file and then update it from the backup copy (as a matter of fact, you have it).

side 1

Heuristic analysis allows for the initiation of unavailable viruses, altogether, when there is no need to wait for the front picking, processing and collecting information about the file system. Yogo day of the pole is in the transformation of the young midst of the emergence of the viruses and the appearance in them of the teams (group of teams), characteristic of the viruses. If there are suspicious commands in the files, or in the entangled sectors, there is always a possibility of infection.

Heuristic analysis, as well as the methods of forecasting, will be based on the principles of inductive logic, based on the principles of the central understanding, the validity of the hypothesis, the level of justice. Obviously, it is possible to advance the steps of justice in the Heuristic hypothesis to predict the development of scientific and technical progress in any direct way, while analyzing the dynamics and trends in the development of scientific advances in science.

For the additional heuristic analysis, it is possible, for the reverse algorithm of the technical process, to set up the most advanced functional groups, which can be included in the warehouse of all functional groups:

We will complete our Heuristic analysis of the early speckle-interferometry.

The program transmits the possibility of carrying out a heuristic analysis in three lines. At the same time, files and system areas of disks can be heard with the mark of unidentified viruses being detected behind the characteristic code messages.

Another principle of polarity is in the heuristic analysis of the significance of officials, how to get involved in practical information and insight.

In 1998 r The system of visual heuristic analysis of numerical matrices Visual HCA was implemented. Additional articles were repeatedly published at conferences in Mexico (China, Belgium) and statistic in foreign and foreign magazines. In 2000, an applied system of visual monitoring was developed for the purpose of providing information to the mechanics of communication from the system of visual heuristic analysis.

Implementation in the given anti-virus program is a special algorithm for the heuristic analysis of allowing the detection of files infected with new types of viruses.

In a number of types, there is such a scheme of well-ordered deterministic rosters, supervised by a highly heuristic analysis, allowing you to complete the grounded solutions and by yourself to finalize the optimization of the adsorption non-intrusive installation. Alle one of a kind of solution, you can really look at your components. It is recommended to prodovzhiti optimizatsiyniy rozrakhunok for the scheme, the following is recommended.

So, at the same time, a very accurate theory is made of mountains, my crops are crocheted in advance of the heuristic analysis of the date exact analysis, strictly based on mathematical theory.

A slid of admiration, as a prelude to a group, which is being shaped for the revision of the same establishment of organizational management, is guilty of a formal mathematical apparatus and a healthy reality to a purely European reality.

Maclaurin will be able to see it, if it’s still very critical 0 14 (divine Rozd. The core can be poured, but not wrapped.

The decision to induce the powerless conflict options to be carried out with the help of the PPP of the optimal design, which is included in the mathematical security of the automated design system. Given the algorithms of heuristic analysis, the EOM gave a selection of the viroblya of the ranking and the vibration of the number of the best options in the AL project, because of the diagnostics, but, navpaki, a compilation of diagnostics, then the vibration. Otrimani results are seen on the thermal annexes in order for the designer to carry out a residual assessment.

In case of a new double-territorial establishment, the extremum of a linear combination of criteria is not taken into account, because there is a lack of Pareto and a residual solution is needed from a heuristic analysis. Inodi is suitable for such a way. One criterion is imposed on one of the criteria, and one should be taken into account, while the other criterion is extremely important.

The name of the group of methods resembles the famous Greek word "Evrika!" - "know!" Heuristic methods are rooted in creative missions and knowledge of fakhivtsy - experts, practical information about the state's testimonies, іkh іntuytsії, on indivіual and collective judgments. Such methods are clearly logical, as additional formalized methods of analysis. The need for this is amortized by the folding and unpretentiousness of a clear mathematical model for the analysis of social and economic processes (I want a lot of such methods and transfer a quick test of mathematical procedures for processing the logical

All heuristic methods can be cleverly divided into expert methods and methods of activating creative thinking (some of them are called psychological).

Expert methods, spiraling into knowledge, judgment and information about fahivts, allowing you to see two groups of analytical tasks:

• 1) rejection of information about specific economic phenomena and reasons, about the key linked sides of business;
• 2) assessments of the characteristic manifestations of strong causal-inherited links, predicting the possible development of social and economic processes and establishing the best rational for a given situation of management decisions.

The first group of employees is asked for an additional questionnaire; For the release of another group, the team will receive a lot of qualified experts. At the same time, there can be vikoristovuvatsya both individual and collective methods of expert evaluations.

individual methods Allowance for the registration of ideas from the opinions of the experts, formed by the skin experts from them, one of them is immediately selected for an additional interview or a questionnaire. There is a shortage of such a move by the field in the form of interconnection of knowledge about all aspects of pre-juvenile problems, in the suitability of the skin of them, such as specific positions, or a school of science.

More effective є storing collective methods, based on the group of young experts - theorists and practitioners, who were kindly informed about the essence of the problem, about the specifics of summery halls, knowledge and types of performance, which may be different points of view. The interaction of the participants in the study gives the opportunity to present the problem from different sides. Among the most popular methods comic method(Virobnichi narads, conferences, seminars and "round tables"), which allows you to play the role of the participants in all the negotiated conditions. Such a method is not enough, for those who have taken the decision, due to the prudence to compromises and psychological pressure of the most authoritative experts, do not necessarily visualize these beautiful options, proponated by the participants. It is often necessary to have a few shortcomings for an additional subdivision of the robot comic in two stages:

• ? the background of the discussion of the problem and the vіlne vіlnе vіlnіvlyuvannya dumok uchasnikіv;
• ? Critical analysis of successive propositions and decisions.

In a larger world, it is allowed to unicate the conformism of experts Del'phi method, on an anonymous assessment of independent experts conducted in several tours (often I don’t know about one or one) with a further statistical sample of the results and updates of the residual solution by a group of analysts.

widely seen methods of collective notebook and bank of ideas, so allow the step-by-step accumulation of ideas and propositions by independent experts, in the distance of types of solutions, practical butt with the possibility of systematizing and evaluating.

Methods for activating creative misinformation Directly to the point of psychological minds, so that they allow people to generate new ideas and shukati the way of dealing with emerging problems. A number of other ways of organizing the creative process during the revision of the economic analysis of the most advanced is the method of "brainstorming".

"Brainstorm" is an effective method of group organization of analytical performance for solutions to any problems, training in the development of creative activity of the participants. Name the win transfer three steps. The first step is to read the formulation of the problem, which will require revision, and the revision of the participants in the creative group. The warehouse of the participants is not guilty of being larger, ale is guilty of including not only the fahivts of the given food, but also the ones who are not tied to any kind of ease. Another stage is the generation of ideas for the solution of the problem posed. A special stage is the establishment of minds for the most vivid creativity when there is an increase in the number of assessments and any criticism of subtle propositions. At the same time, do not bother to navigate directly a joke of ideas and criteria for evaluating. The head meta - tse is the maximum number of visually quirky propositions and young people, all the smells of guilt are fixed. Visiting fantastic and building absurd ideas. The triviality of this stage is not to blame for the change in time of the year, as the activity of the creative work, as a rule, begins to calm down. The third stage is the decision of analysts - organizers of the "storming" of the classification of subtle propositions, views, evaluation and development of new combinations of the most promising ideas.

Modifying the "brainstorming" method є method of si nektiki. The term "synectics" itself means victorious for the creation of creative workers in the same range of young, often different elements, which are created insane. From the classic "brainstorming", the synectics is based on the organization of the group in the creative activity of the members, on the basis of specific acceptance of ideas, on the assumption of critical discussion of the stage of failure At the same time, the guilt of the group includes not just professionals, but creative specialties, who are ready to stand up to their positions, and who will have different psycho-social characteristics (entusies, conservatories, optimism. Typical for the synectics is the development of verbal verbal receptions from the activity of the target: analogies (the knowledge of solutions based on the analysis of similar problems in other areas, the idea of ​​thinking in ourselves, myths, Kazakhs), from the analysis of the problem and the reasoning of the problem based on the power of ideas), ideology (to the point of view of the ideal result). It also means that for the synectic group of experts it is even more important to prepare for the front, to think about it, and because of the growing criticality of the discussion, you can simply block the generation of new ideas.

Morphological method. The whole method is to look at the assessment of the internal structure of the previously discussed privatization and general decomposition of the problem, to look at the environment of the plant, to look at the possibilities of combining the solutions for the synthesis of the complex

Theory of solving wine problems(TRIZ). With the help of the TRVZ methodology, the development of technical systems and the establishment of practical methods for the development of wine problems on the basis of detection and use of problems in such systems for achieving the ideal final result. Nini TRIZ has transformed itself into a universal methodology for analyzing business problems in various regions, including in economics. Activation of creative aim at the same time reaching the structure of

• 1) for whom the system is designated, for which elements are stored, for which functions and how smelly are combined;
• 2) the links of the elements of the system and the functions of the corny, the marnims, and the shkidliv;
• 3) both elements, the function of that connection is possible to change, but it is uncomfortable to change;
• 4) how many options are available for changing system elements, functions and connections;
• 5) how the changes will ensure the complete functionality of the system as a whole, and how the supervariety of the system will occur and will weaken;
• 6) how do you like to polish the changes in case of one-hour weakened or minimizatsii of the wipes.

To stimulate creative activity and organization of systematic self-directed robots, expert analysts often go to the length of their own rules. rule 24 I punish you that all 24 years in advance, the analyst is guilty of thinking about pre-sluggish problems. Rule 25 - for a successful revision of the delivered plant, it is necessary to visit at least 25 ideas. Rule 26 - in the English alphabet there are 26 letters, and in the sense of a clue to yourself, you need to think, on which letter you will need to fix the key to solve the problem and the word.

Heuristic methods of analysis

Look at your life, ymovirno, people started to play, like a persh for everything that beat you, but a new one is highly suspicious of uyava, original and unsupported judgments, ideas, like the power of a very reckless, deceitful. Such a person, as a rule, is called a creative specialty. And the building is up to the generation of new ideas є all are presented to one of the most important signs of creative specialty.

І in schools, і in general and medium-sized special primary mortgages, unfortunately, the development of іntuіtsії, health to the generation of new ideas give lack of respect. Teachers mostly respect the logical methods of revising the buildings, including in the process of revising creative directors.

Rozrakhunkov methods operate only with single-song information, which is used for analysis of control systems of a velma. For the analysis of the state dіyalnosti, there is a great significance of the development of Heuristic methods, which are directly related to the rejection of the characteristics of the subordinate state. The methods of euristics are grounded by the head rank on the admissions and intuits of the fahivts, of the individual and collective judgments. Among the Heuristic methods, it is possible to see the assessment and assessment and analysis methods.

Heuristic methods are widely used in robots for personnel management, organizing management and organizing behavior.

Mind, that you need to be victorious in Heuristic methods, can be characterized by the offensive rank:

The clear nature of the on-going information, which can be described behind the addition of economic and social parameters, the availability of representative and reliable views of the characteristics of the information;

The lack of significance of the given data for the analysis is great;

The visibility of a clear subject description and mathematical formalization of the subject of the assessment;

Marriage for hours and needs for adolescence from formal models;

The availability of technical features with specific characteristics for an analytical model;

Extremeness of the analyzed situation.

Heuristic methods of analysis are a special group of taking in the collection and processing of information, so that they can spiral onto the professional thought of a group of fahivts.

Heuristic methods are often called creative, so as the stench spirals on the creativity of a group of people. Locking up the hopes and ruling of the analysis in the case of Heuristic methods є the correct test of the expert. Regardless of the goals and the directness of the group of experts, they can be of the same type, or include representatives of the small groups of knitted fauns, and some of them are simply connected. Napriklad at formuvannі groupies ekspertіv for analіzu tehnologіchnih rozrobok in neї vklyuchayutsya technologists SSMSC profesіyno mozhut otsіniti tehnіchnu novelty rіshennya, ekonomіsti, SSMSC otsіnyuyut Yogo efektivnіst, mehanіki, SSMSC mozhut dati otsіnku mozhlivostі realіzatsії novoї tehnologії on nayavnoї virobnichoї Bazi`, robochі - vikonavtsі novoї tehnologії ... When evaluating the quality of the product and taking a drink at it, before the warehouse, the group of experts includes not only merchandise, ale and virobniks and assisted products. At the same hour, when developing a technical solution at the first stage, before the warehouse of a group of experts, there are only a few fahivtsi of a specific profile.

In practice, we agreed to complete the folding methods and form the group of experts:

For formal criteria, if you have the qualifications, experience of the robot, the triviality of being in one team; Psychological assessments of the specialty are carried out here according to the data of the sociological service of the organization (such as such), for example, the building up to the creative mind, the constructiveness of the message, etc .;

On the basis of self-assessment of specialness, taken into account when questioning, in general, the expert himself assesses his own abilities, including quality, analytical and constructiveness of purpose. Such a review of the expert will be updated with the values ​​of the self-assessment of the maybut expert - underestimated, envied or adequate, which is carried out with special

psychological review of experts;

On the basis of assessments of individuals, matched with the applicant, if the professional and special qualities of the faction are evaluated by the faults similar to the profile, the helpers of the services, the experts, who are realizing the solution of the examiner;

By the method of vidboru (vibrating), which, in the capacity of experts, can be without problems (for example, assisting in products and services).

Often, when analyzing the efficiency of the state-endowed sub'єct, the warehouse of the group of experts should include the cores of the rіvnіv rіvnіv and pratsіvniki. For example, this is how a group of experts is formed when choosing a strategy for developing virobnstva, changing systems and stimulating, reforming systems of energy and visibility, re-energizing organizational structures.

In such a rank, when choosing experts, they widely use both formal and psychological methods of selection. In conjunction with the cym, heuristic methods are often called psychological.

(Melyukhova Yana) 1) Method of typology grunting on scho has become a popular theory of positioning. The main idea of ​​the theory of polarity in the ready-made, single for all pictures of standard situations and solutions. The head of the analyst of the field at the vibration of the position, the general procedure for the analysis of the singular parameters, and the rejection of the standard solution, the proponents of the method. Practical additions to the theory of the ZKG matrix, McKenzie and іn. The technology for the implementation of the method includes the following steps, such as:

Assessment of the analyzed object according to the given parameters;

The position of the object in the typological scheme is based on the value of the parameters;

scheme by the type of the analyzed object.

When prompting a typological scheme, it is possible to choose two parameters and more. Parameters can represent both simple power and complex. The perspective of the market, which is characterized by the size, the rate of growth, the level of satisfaction of the needs of the population, the competitiveness, the level of price, the rate of growth and

etc. The yak can be seen from the aimed butt, the parameters can be assessed. The position of the analyzed object (objects) on the typological situation is possible at the viglyadі tієї chi іnshoї vіdmitini (points, cil, etc.).

With the appearance of the outlets in specific areas, the registration of typological networks allows the type of the analyzed object and the speedy ready-made recommendations to be made. However, with the typology method it is necessary to protect it in the region. It is necessary for mothers on respect, which are universal "recipes" to finish with a focussed prostate, which is in contrast to the solutions of creative workers, and altogether a bit of harshness is due to the imposition of recommendations from the velmi. More beautiful than the nobility, like finding out and virishity problems, no more vitality in ready-made recipes for success. On the author's thought, depriving the given method of typology in the given assessment methods will allow to characterize the situation and know the acceptable options for predictive management decisions.

(Olya Kiselova) 2) Method of expert assessment to spiral to the public assessment by an expert group by way of a statistical survey of individual, independent assessments, made by experts. The members of the group in the whole range can be of equal rank, so they can be insured in case of the results of the examination.

When typing experts with such vimogs, such as:

High level of foreign erudition, volodinnya by special knowledge in the analyzed area;

Revealing of the singing practical and (abo) pre-admission to the given problem;

Building up to an adequate assessment of the tendencies for the development of a pre-sluggish object;

The prevalence of anticipation, feedback in the specific results of the assessment.

A friendly mind for the robot experts is set up as a result of the previous instruction, the introduction of the methodology of preliminaries, the provision of additional information about the object of analysis.

(Olya Prilepa) 3) Method of expert committee Submissions on the emergence of a single collective thought were specially selected by experts for an hour to discuss the problem posed and the alternatives, as a result of the singing compromises.

With the victorious method of the expert committee, it is not just a statistical processing of the results of the individual ball assessments of all experts, but the exchange of thoughts for the results of the expert assessment and the refinement of the assessments. There is a lack of such a procedure in the field in a strong infusion of authority on the thought of more participants in the examination.

In contact with

You can use anti-virus software to protect yourself, do not let you know about those that have been installed. However, in the Danish hour, there are even more anti-virus programs, so you will be able to get your own vibe. According to the possibility of priming and installing the programs, the maximum steps were taken for the user to choose from viruses, it is necessary to learn the methodology to be stuck with these programs.

There is a small number of ambush techniques to detect those from viruses. Anti-virus programs can implement only those methods of combination.

Hardware zahist from viruses

In addition, a large number of anti-virus programs will automatically update infected programs and entangled sectors.

Ob'єkti infected

For the first time, we have already informed about the development of types of viruses and about the methods of their expansion. Before you start to look at the anti-virus settings, overwhelm the area of ​​the file system and the computer, as it is likely to become infected with viruses, and it is necessary to convert:

Vikonuvani program files, drivers

The head of the clerk record and the clerk sector

Configuration files AUTOEXEC.BAT and CONFIG.SYS

Documents in the format of the text processor Microsoft Word for Windows

If the resident virus becomes active, it will place its permanently active module in the operating memory of the computer. To that, anti-virus programs are guilty of reconverting the operational memory. So, as a virus can be victorious, it is not only the standard memory, then it’s bazano viconuvati an inversion of the upper memory. For example, the Doctor Web antivirus revolves the 1088 Kbytes of operational memory.

scan

The simplest technique is to joke viruses, but it’s the fact that the anti-virus program looks at the files after the last glance to convert the files into the joke of the signatures of the viruses. Given the signature, the unique nature of the electronic data should be recognized, so that the virus can be detected, and not be used in other programs.

The signature of the virus must be completed in a foldable manner. The signature is not guilty of avenging normal programs that are not infected with the cyme virus. In general, there is a lot of mercy on the matter, if the virus appears in an absolutely normal, non-infected program.

Obviously, scanning programs do not necessarily take into account the signatures of all types of viruses. The smell can, for example, take only the control sums of the signatures.

Anti-virus scanners, as you can see viruses, are called polyphages. Nyvidomishoyu program-scanner є Aidstest by Dmytro Lozinsky. Aidstest re-verifies the detection of viruses by their signatures. To that, only the simplest polymorphic viruses are found.

At the first address, they were asked about the so-called encrypted and polymorphic viruses. Polymorphic viruses will increase their code when they are infected with new programs or the enchanting sector. If you see two examples of one and the same polymorphic virus, then the stench may not be lost in one byte. Yak inherited, for such viruses it is unfortunate to see a signature. Because of this, anti-virus scanners cannot detect polymorphic viruses.

Anti-virus scanners can only detect viruses as well as bullets in front of them, and for which a signature is assigned. Thus, the victorious program scanners do not steal your computer from the penetration of new viruses.

For effective testing of anti-tier programs, which implements the scanning method, it is necessary to continuously update them, to accept the latest versions.

euristic analysis

Euristic analysis is an unmistakably new method for detected viruses. It is allowed to detect earlier unavailable viruses, moreover, it is not necessary to collect data about the file system in advance, which is the method of detecting changes.

Anti-virus programs that implement the method of heuristic analysis, rewrite the programs and enchant sectors of disks and floppy disks, add the code characteristic of viruses to them. So, for example, a Heuristic analyzer can change the code that will install a resident module in memory.

The anti-virus program Doctor Web, which is included in the warehouse for the set of JSC "DialogueNauka", is a tedious heuristic analyzer, which allows a great number of new viruses to be discovered.

As a heuristic analyzer, it’s possible to get a virus infection from a file or an entangled sector. Bazhano doslidzhuvati such files for the help of the remaining versions of the anti-virus programs themselves or send them for a detailed introduction to AT "DialogueNauka".

The set of IBM AntiVirus includes a special module, which can be used to detect viruses in the security sectors. The whole module is a patented technology (patent-pending neural network technology from IBM) of heuristic analysis and allows the presence of infections in the virus-infected sector.

viyavlennya zmin

If a virus infects a computer, it is necessary to tamper with snaps on the hard disk, for example, add its code to the file, then add the program-virus to the file AUTOEXEC.BAT, change the file-locked file sector, the shutter.

Anti-virus programs can, in front of the memory, store the characteristics of all areas of the disk, which can be attacked by a virus, and then periodically change them (it looks like they are called revision programs). As soon as there will be a change, the virus can attack the computer.

Allow the revision programs to memorize in special files the image of the head copyright recording, the enchanting sectors of the logical disks, the parameters of all monitored files, as well as information about the directory structure and the numbers of corrupted disk clusters. You can change the characteristics of the computer - the installed operating memory, the number of disks connected to the computer and the parameters.

The revision programs can reveal more viruses, even quiet ones, as they did not see them before. Viruses, scho infect program files only when they are copied, revision, as the rule cannot be detected, because I don’t know the stink of the parameters in the file, as they were before copying.

However, it was not all the changes to the invading viruses. So, the entangled record can be changed with the updated version of the operating system, and with the programs, you can write down all the middle of your data file that has been created. Command files change more often, for example, the AUTOEXEC.BAT file will change until the hour of installing a new software security.

The revision programs will not help the virus, if a new file has been written into the computer. True, if a virus is to infect with programs that have already been instilled with a revizor, it will appear.

The Microsoft Anti-Virus (MSAV) revision program is easy to access before the MS-DOS operating system warehouse. The main ones, and can be easily singled out, are those who do not need extra money on it.

Significantly more development is needed for control over the Advanced Diskinfoscope (ADinf) revision program, which is included in the AT "DialogueNauka" anti-virus set before the warehouse. More detail is visible in the offensive section, and at the same time, it is very appreciable, right at the same time from ADinf you can use the optional ADinf Cure Module (ADinfExt). ADinf Cure Module I have selected earlier information about the files to update them for hitting unidentified viruses.

Obviously, not all viruses can be seen by ADinf Cure Module and other software tools, based on the control and periodic changes of the computer. For example, as the new virus encrypts the disk, how to keep the OneHalf virus, then it can be seen without decrypting the disk more quickly for everything before the information is lost. Viruses of this type can be seen only by the respected vivchennya fakhivtsy and the inclusion of modules for fighting with them in special polyphages - Aidstest or Doctor Web.

At the time of the book's writing, we see that anti-virus programs-revisions are not valid for detecting viruses in document files, so as the smell of your sutta is constantly changing. A number of programs write the vaccine code in them to stop working. In order to control them, you have to go through the program-scanners or heuristic analysis.

resident monitors

There are many classes of anti-virus programs, which constantly work in the operational memory of the computer, and display all of the agendas of the program, as well as display those programs. Such programs are called resident monitors or watchmen.

The resident monitor will change the koristuvachev, as if the program would try to change the enclosed sector of the hard disk or the floppy disk, the file is open. The resident monitor will let you know when the program is loaded into the operative memory, the resident module, etc.

A large number of resident monitors allow automatically converting all programs to be launched on infected with viruses, in order to display the scanner's functions. Such a change will take a few hours and the process of entangling the programs will be adjusted, but then you will be able to remember, as a virus cannot be activated on your computer.

Unfortunately, the residence monitors may be even more short-lived, as they are not very useful for class programs.

There is a lot of programs, you can find no revenge on viruses, you can find out how to respond to the residence monitors. For example, the LABEL team is very special and has a tribute in the enticing sector of the monitor.

Tom of the robot will be constantly re-privatized by the anti-virus drastic updates. In addition, the koristuvach is guilty of being guilty once virasuvati, chi viclikano tse spratsovuvannya virus chi ni. As a demonstration practice, early on the keystuvach turns on the resident monitor.

I nareshty, who has the least number of resident monitors in the field, in that the smell of guilt is permanently locked into the operative memory and, also, change the amount of memory available to other programs.

The warehouse of the operating system and MS-DOS also has a resident anti-virus monitor VSafe.

vaccination program

In order for a lyudin to be able to identify deyakykh ailments, to shy away from splinters. There is a way to get programs from viruses, if you want to get a program, you need a special control module to keep up with the whole world. At the same time, the control sum can be changed by the programs, if only for those characteristics. If the virus is infected, the file is vaccinated, the control module changes the control file to the file, and after all, the control module changes.

It’s a pity, on the mind of people, the vaccination of the program in bagatokh vipadki is not all of the infected. Stealth virus is easy to cheat with a vaccine. Infected files can also be cleaned, so the vaccine is not infected. Tom, we will not get rid of the vaccines and continue to look at them for the sake of the victim.

Apparatna zahist vid viruses

On the current day, one of the best ways to kill computers from attacks from viruses and hardware-software is one of the best ways. The stench is a special controller that can be inserted into one of the rose's expanded computer and software for security, which is a kernel of a robot controller.

For the fact that the controller of the hardware connections to the system bus of the computer, we will take over the control over the usages of the worms to the disk system of the computer. The program for securing the hardware device allows the user to enter areas of the file system, as it is not possible to change. You can recover the main enqueued record, enqueued sectors, viconurable files, configuration files, etc.

As soon as the hardware-software complex emerges, if the program is damaged, the ruiner is installed, I can see about the koristuvachev and I will block the computer's robot.

Hardware control over the computer's disk drive does not allow viruses to mask themselves. Yak tilki virus to show itself, it will be immediately apparent. With a whole lot of absolutely baiduzh, like a practical virus and a coat of arms for access to disks and floppy disks.

The hardware-software will allow the user not only to destroy the computer from viruses, but also to immediately assign the Trojan programs to the robot, aimed at ruining the file system of the computer. Apart from that, hardware-software will allow you to clean up your computer as an unqualified criminality and evil-doer, the stench will not let you see important information, format the disk, change the configuration files.

In a given hour in Russia, only the Sheriff hardware-software complex is being rolled around. If the computer is infected, it is necessary to allow koristuvachev vitrachati for less than an hour for anti-virus control of the computer by means of special software tools.

Behind the cordon, it is more expensive to carry out hardware-software purchases, but the price is very high, but not from Sheriff and to become hundreds of American dollars. Kilka axis is the name of such complexes:

Naming the complex	Virobnik
	JAS Technologies of the Americas
	Leprechaum Software International
	Digital Enterprises
	G lynn Internati onal
	Swabian Electronics Reutlingen
	Telstar Electronics
	Bugovics & Partner

In addition to displaying its main functions, hardware and software help the computer operator to forget about the new additional service. The stench can smelt keruvats between the access rights of young people to computer resources - hard drives, disk drives, etc.

Zakhist, embedded in the BIOS of the computer

Bagato firm, which let the system boards of computers be released, have become the easiest ones to get into them. You can allow control of all the corruption up to the head of the enchanting recording of hard disks, as well as to the enchanting of the sectors of disks and floppy disks. If the program will try to change instead of the enticing sectors, if the program will try to change it, then the client will be taken away from it as soon as possible. With a lot of wines, you can allow the price of a zmіna or a fence of yogo.

However, such a control cannot be called a reference control at the hardware level. The program module, which is responsible for controlling access to the locked sectors, is located in the BIOS ROM and can be used to deal with viruses, so that the stench will hide the locked sectors, and be executed without the average before the ports are inserted / inserted into the drive of the controller.

To detect viruses, when you turn on the anti-virus control of the BIOS, change the operating system in the independent memory (CMOS memory) of the computer.

Viru Tchechen. 1912 and 1914

Even more secure resident encrypted viruses. You should know in the BIOS ROM the text rows of Megatrends and AWARD. As soon as the joke ended successfully, it stinks, the BIOS of the AWARD type is installed in the computer, or AMI, it enables control over the enchanting sectors and infecting the head enchanting record of the hard disk. approximately through the month of the infection of the virus was seen by the information from the first hard drive

The simplest thing about the hardware device is to connect all channels from the computer through which the virus can penetrate into the new one. If the computer does not connect to the local mesh and the modem is not installed in the new one, then it will be okay to connect the storage on floppy disks and the main channel of the correct virus in the computer will be crooked.

However, the connection is far from necessary. In most cases, normal robots need access to drives or modems. In addition, infected programs can penetrate into a computer through a local net or CDs, and when connected, it can sound the sphere of a computer’s storage.

Virus visualization method

Viyaviti virus on a computer - only half of the right. Now you need to see it. There are a lot of anti-virus programs that can detect viruses and can be seen. Learn two basic methods, how to use anti-virus programs for the visualization of viruses.

Yaksho viyavili virus, reconverting the viconuvane files with extensions from the COM and EXE extensions, then reconverting all the types of files in which the viconuvane code is located. Files with extensions SYS, OVL, OVI, OVR, BIN, BAT, BIN, LIB, DRV, BAK, ZIP, ARJ, PAK, LZH, PIF, PGM, DLL, DOC

You can now convert all files on your computer's hard drives. It is possible to change the infection of the existing file, changing its expansion. For example, the EDITOR.EXE file was renamed to EDITOR.EX_. Such a file will not be changed. As soon as you change it back, the virus knows you can activate and expand in the computer

First, the best method of transmission has been expanded, and the anti-virus program is already visible to the virus. You need to have a correct version of the virus, you need to have a new version of the anti-virus.

Another technique allows the capture of files and the entrapment sectors infected with previously unidentified viruses. For the whole anti-virus program, it’s old, before the viruses appear, I am guilty of analyzing all the files that were downloaded and keeping a lot of useful information about them.

When the antivirus programs are launched, they will re-select the data about the files and the beasts from the data that were previously discarded. If there are inconsistencies, it is possible to file a virus infection.

In general, the anti-virus will be able to update the infections of the file, which is for the whole vidomosti about the principle of the introduction of viruses in the file and information about the given file, which I will remove before it is infected.

Deyaki viruses infect files and entangled sectors, substituting their code for a part of the infected object, so that it infects the object irrevocably. Files and closed-up sectors infected with such viruses cannot be found in the first method, but as a rule they can be updated for another method. If you want to update infected files, do not use antivirus programs for additional anti-virus programs;

From the head blocking block and the blocking sectors on the right, it is often folded. As long as the anti-virus program is not in automatic mode, you will be guilty of updating it by speeding up the commands FDISK, SYS, FORMAT. Manually renewing the enchanting sectors in the future will be described in several ways.

A group of viruses, which infect a computer, become part of the operating system. If you just see such a virus, for example, having updated the infection file from a floppy disk, then the system can become quite often, or rather, non-standard. Such viruses are required to be treated with the use of the first technique.

Yak the butt of such viruses can be brought to the addicting OneHalf viruses and the VolGU group of viruses.

OneHalf virus is encrypted step by step instead of a hard disk. If a virus is found self-defeating in memory, then I will overwhelm all the corruption to a hard disk. Once, if the program is mapped to the same encryption sector, the virus will decipher it. If you see the OneHalf virus, the information on the encrypted part of the hard disk will not be available.

Virus VolGU is not encrypted, but it is not safe, not OneHalf. The leather sector of the hard disk is not only the data recorded in the new one, it is also possible to take revenge on the additional information. Vaughn is the checksum of all bytes of the sector. Qia control bag vikoristovuyutsya for reconversion of safety information.

Call me, if the program goes to the computer's disk system, reads and records only the data, the control sum is corrected automatically. Virus VolGU, I rewrite all programs to the hard disk and when writing data to the disk, control sum of sectors.

If the virus is active, it allows you to cheat the sector with the wrong control sum. It’s easy to see such a virus, because the sector with the wrong control bag will not be read. The operating system will tell you about the pardon of reading from the hard disk (the sector is not known).

Preparing for military training

Corrupt computers are guilty of being guilty of waiting for a possible attack of viruses, and not checking to the rest of the blame, if the virus already appears. Anyone who knows how you can make it more efficiently and efficiently.

Who has such a training?

¨ Prepare the system diskette later. Write on it anti-virus programs-polyphages, for example Aidstest and Doctor Web

¨ Continuously update the versions of anti-virus programs recorded on the system diskette

¨ Periodically check your computer for additional anti-virus settings. Control all changes on the disk with additional revision programs, for example ADinf. Change new and change files with polyphage programs Aidstest and Doctor Web

¨ Reverse all floppy disks before the vicistories. To rewrite, use more new versions of anti-virus programs

¨ Revise all the files to be registered on the computer

¨ If you need a high level of money to get out of the viruses, install an apparatus controller in the computer, for example Sheriff. The sleeping room of the hardware controller and the traditional anti-tier tools allow you to maximize the security of your system

System floppy disk

Zazvychay in komp'yuterі installed two accumulators on dull magnetic disks. One is for 5.25 "floppy disks, and the other is for 3.5" floppy disks. Operating system MS-DOS, as well as operating systems Windows, Windows 95, Windows NT and OS / 2 use the names A: and B:. For example, from the drives of the computer A:, and for B:, lay down the computer's hardware.

As a rule, you can change the name of the drives. For this, it is necessary to open the case of the computer and to bridge the spindle of roses. Since this is such a possibility, then the robot should be left with the help of a technical fahivtsya.

Nakopichuvachi on magnetic disks with a size of 5.25 inches step by step go out of life, so in new computers only one accumulator is installed on dull magnetic disks, insurance on floppy disks with a size of 3.5 inches. In general, there is a vin maє im'ya A: disc B: відсутній.

You can lock the computer behind the additional system diskette only from the A: drive. In such a rank, to make the system diskette to your computer, take a diskette of a size.

Isnu bezlich program, scho allow you to create a system floppy disk. Such programs enter the warehouse of all operating systems - MS-DOS, Windows 3.1, Windows 95 and OS / 2 and others.

The simplest programs for the preparation of system floppy disks are the FORMAT or SYS commands, which can be included in the warehouse of MS-DOS and Windows 95 operating systems;

Vikoristannya commands FORMAT

The FORMAT command displays the format of the floppy disk and can be written to the file of the operating system. When formatting rogue disks FORMAT, the screen displays the size of the drive on the diskette, and the form of the system area - the old sector, the table of file distribution and the root directory.

For an hour the formatting of the floppy disk, all information, written on it, is erased. So if FORMAT will re-write the zapped sector onto the floppy disk, then if the bullet has been infected with the zapping virus earlier, the virus will be seen. You can say that the FORMAT team will see the main function of the antivirus - it will see the shkіdlivі viruses from the diskette.

When the FORMAT command is wicked, you can set a large number of different parameters. You can find your description in the fourth volume of the series "Personal computer - croc by croc", which is called "Who blame the nobility about your computers". At the bottom of the list, it is only possible to describe the few parameters that we know of:

FORMAT drive:

For the drive parameter, set the name of the drive, which will be formatted for the diskette. The / S parameter means that when formatting a floppy disk, the main files of the operating system are transferred to it, and the diskette becomes the system one. For the preparation of the system diskette, the following parameter must be included.

As they said, the FORMAT command saw the formatted floppy disks of all recorded on these files. Name FORMAT, the information will be written to the diskette, which allows you to update the file from its file whenever you need it.

To update the files, you can see the format of the floppy disk after the hour, use the UNFORMAT command

If you firmly remember that you will not be able to restore it, you can speed up the format of the diskette by using the additional / U parameter.

You can speed up the process of preparing the system diskette by adding the FORMAT command with the additional / Q parameter.

The process of preparation of the system diskette is described with a report. Enter the offensive command:

The screen prompts you to insert a floppy disk into drive A: :

Insert new diskette for drive A:
and press ENTER when ready ...

Honor the formatting process. On the screen, the percentage of the Vicon's robots will be displayed.

Formatting 1.2M
77 percent completed.

After finishing the format, the main files of the operating system are written to the floppy disk. Then you can enter a floppy diskette. The mint is guilty of a vengeance of no more than eleven symbols. For the introduction of the tricky key ... If you don’t use a floppy disk, press a key at once:

Format complete.
System transferred

Volume label (11 characters, ENTER for none)?

Then, on the screen, there is a statistical information: the diskette memory, the space, the use of the operating system files, the available space. As soon as on the diskette, the filthy sectors that are inaccessible to the victorious are displayed, the total amount in bytes is displayed. The lower is the size of the sector in bytes, the number of valid sectors on the diskette and the serial number:

1,213,952 bytes total disk space
198,656 bytes used by system
1,015,296 bytes available on disk

512 bytes in each allocation unit.
1,983 allocation units available on disk.

Volume Serial Number is 2C74-14D4

Format another (Y / N)?

At any time, the preparation of the system diskette can be completed. If you don’t plan to insert the diskette of the system floppy disks at once, press the key ... Please insert another system diskette, press the keyboard and repeat the descriptions by us during the process.

Vikoristannya command SYS

As long as you have a clean, formatted floppy disk, you can do everything with the system system behind the help of the SYS command. To do this, insert the floppy disk into the computer's floppy drive and enter the next command:

SYS drive2:

The SYS command has one binding parameter - drive2... This parameter is responsible for specifying the name of the drive, in which the system diskette is prepared. You should enter yak parameter drive2 im'ya A: chi B:.

optional parameters drive1і path Viznachayut roztashuvannya system files on disk. If you don’t include any parameters, the SYS command will take the system files from the root directory of the streaming disk.

Writing anti-virus programs to the system floppy disk

The main files of the MS-DOS operating system are stored on the system diskette: IO.SYS, MSDOS.SYS, COMMAND.COM, DBLSPACE.BIN. If the system diskette is available in the MS-DOS operating system, for example, the IBM PC-DOS, then the names of these files can be used.

The files IO.SYS and MSDOS.SYS are the core of the operating system. The COMMAND.COM file is called the command processor. This is the program itself, as it is to bring on the computer screen the system of the requested and the vison of the command of the operating system. The remaining file on the system diskette is DBLSPACE.BIN. I will take revenge on the expansion of the operating system, as I will not have access to the damaged disks of the DoubleSpace system.

The main files of the operating system - IO.SYS, MSDOS.SYS may not show the "attachment file" attribute and will not appear with the DIR command. Give the DIR command the / A parameter.

For this purpose, when we got the system floppy disk, there was a lot of free music on it. Sumarny obsyag, as it is, having enclosed the main files of the MS-DOS operating system - IO.SYS, MSDOS.SYS, COMMAND.COM, DBLSPACE.BIN become close to 200 Kbytes. In such a rank, if you vikoristovuvat floppy disk with a high capacity, then your ordered will appear more than a megabyte of free space.

Write to the system diskette the software that is required for testing and updating the operating system. In the first place, it is necessary to write down anti-virus programs to check the virus and program for reconfiguring the integrity of the file system. It is important to write down the FORMAT and FDISK commands - the stench can be used for manual updating of the system. For convenience, you can additionally write a shell to the system floppy disk, for example, Norton Commander, or any text editor.

The tables have been guided by programs, which can help you with the renewal of your computer. Bazhano write all їх to the system floppy disk. If the stench does not fit on one system floppy disk, prepare another floppy disk and write down the programs on it.

	Disc editor. Allowing to re-look and edit, be it information, recorded on disk, including system areas. Disk Editor allows you to edit the head overwrite sector, override sectors, FAT tables, directory structures and files

In some cases, for access to hard drives of a computer, you can choose special drivers or some programs. It is generally necessary to write the system diskette to the prepared system diskette. The stink was automatically connected when the computer was locked from the system floppy disk, and the CONFIG.SYS and AUTOEXEC.BAT files were opened on them, having written down the commands for locking the necessary drivers in them.

As soon as the computer is connected to read CDs, write it to the system floppy disk without the software, which is necessary for the first time. For MS-DOS, you need to write the driver and add the MSCDEX program to read the operating system. Access to the annex to the reading room will allow you to quickly update the program, recorded on CDs.

The operating system Windows 95 is not required by the MSCDEX programs, however, as the graphical shell of the whole system cannot be used, MSCDEX still needs to be connected

In order to do this, they prepared a system floppy disk and wrote down all the necessary programs on it, and then I will write to it. For those on a diskette with a size of 5.25 ", you need to glue the holes on the edge of the floppy disk, and on a floppy disk with a size of 3.5", you will be able to see it. I will write down to give you a guarantee that you don’t use a floppy disk or viruses to penetrate it. So, like a floppy disk, one can run out of tune, then it is more beautiful than any mother's diskette of identical system floppies.

Entangling from the system diskette

Check to lock the computer from the system diskette, you need to set the priority to lock the operating system from the dull magnetic disks. The priority of securing the operating system is in the CMOS memory. Just start the Setup program. You can learn more about the Setup program from the fourth volume of the series "Personal computer - croc by croc", which is called "We are guilty of the nobility about their computers".

Find viruses, so change the priority of locking up your computer. For the whole stench of the data, recorded in the CMOS memory. The attachment of such viruses can be Mammoth. 6000 and ExeBug viruses. Tsi viruses are included in the CMOS memory of a disk drive, which can be switched on at the same time, even if the program is ready to read or write the information to a floppy disk. If the koristuvach is zamagєtsya zavantazhiti computer from a floppy disk, zavanazhennya bude vikonuvatisya from a hard disk, so like a drive for inclusion. Virus removes control, and then the virtual computer is locked from a floppy disk.

At the same time from the point of view of the koristuvach, everyone is watching. Win back, so the operating system is locked from a diskette, but until an hour the virus is already in the operative memory and control of the computer's robot.

Tom bezposeredno before the time you wikonuvati zavanazhennya MS-DOS from the system floppy disk, change it, instead of CMOS memory is installed correctly. To run the program to install the BIOS parameters and change the indication of the type of drives there, as well as the procedure for locking up the computer.

Insert the system floppy disk into drive A: and restart the computer. If you suspect the appearance of viruses, to re-install it you need to turn on and turn on the computer's life, or press the "Reset" button on the computer case. Deyakі Virusi are re-entangled for an additional key It can be lost in the operative memory for such a lock from the system diskette.

For a cob test of a computer, you can think of an operating system locked from a floppy disk. At the same time, the LED drive A: is guilty. The process of entangling from a diskette goes through three more times, below from a hard disk, so you will get three more steps. If the backup of the operating system is completed, the screen will appear as soon as possible.

Then the operating system will ask you for the exact date and hour. The date and hour will not be powered up in the same way as on a diskette (disk) in the system configuration file AUTOEXEC.BAT.

If you don't want to change the date and hour, get two keys ... At all, the date and hour will be lost without a change, and the system requested MS-DOS will appear on the screen:

You can install the empty AUTOEXEC.BAT file on the system diskette, so that the date and hour will not be powered up, and if the operating system is locked, the system will immediately appear on the screen.

Chi can be penetrated by viruses

Even if the robot does not periodically carry out prophylaxis and cleaning of computers from viruses, the possibility of taking in information, so that it is possible to save and manage the operational environment, is much less real.

Negative inheritances of your nondiality can be positive, in the absence of such a virus to be consumed in a computer. You can spend some of the information from the files, which are stored in computers, or some files, or browse all the files on the disk. Ale naygirshe, if the virus has made small changes in the tribute files, as there may be some not mentioning them, but then bringing them up to pardon in financial or scientific documents.

Robots from the prevention and control of computers from viruses can include the following steps:

w Reinstall the software, securing only one from the distributions

w Install on all of your floppy disks.

w Interchange the exchange with programs and floppy disks, change such programs and diskettes for the appearance of viruses

w Periodically recalculate the operative memory and disks of the computer for the presence of viruses behind the addition of special anti-virus programs

w Select the backup copy of the information

Chi do not know people who do not know

Anyway, come in to the hijacker not to help clean up the computer because of the penetration of viruses, if you don’t try to rewrite everything and sign up for a new file. On the current day, such a change can be made only for the additional help of anti-virus polyphagous programs.

Post-release of all new and new versions of anti-virus programs. Bazhano, besides, there was no joke about them, but not only from domestic viruses, but also from the heuristic analysis of the revised programs and the enticing sectors. Windows to allow files infected with new, unavailable and non-infected viruses.

Unfortunately, the anti-virus programs cannot give a new guarantee of the day-to-day to be converted to software-safe viruses and more than Trojan programs or logical bombs. Record on your computer the program for the safety of the unhomed person

Great organizations have a special computer for installation in a new comprehensive software security, for example, computer igor. The whole computer is guilty of being isolated from other computers of the organization. In the first place, it is necessary to turn on one of the local fences and the fence for the users not only to copy them from the programs, but also to write them on a new file from their working floppies, long ago without stolen from the records.

For an hour the robots will be able to pick up the software monitors, for example the VSafe monitor, and log in to the MS-DOS warehouse. As soon as the program appears to be infected with a virus, or else to revenge a logical bomb, the monitor will tell you about any unauthorized actions from the side. It’s a pity that the VSafe-type monitor programs can easily be deceived by viruses, so it’s necessary for the software-hardware device to be deceived.

Before the warehouse of the anti-virus kit "DialogueNauka" includes a software-hardware complex for the Sheriff server. Apart from us, the visitor of all the functions of the monitors' programs, is a little more expensive to color. For the rakhunok of that scho control of the computer, you will be provided with a special controller, and you will not be able to fool Sheriff.

Yak to clean up the floppy disks I will write

You can clean up your floppy disks from the record. Zakhist pratsyuє on the basis of the computer's hardware and it is not possible to turn it on by software methods. To that, the virus cannot infect the zapped sector and the files stored on the diskette with the entry inserted by the zapper.

All distributions of software security, recorded on floppy disks, are guilty of being stolen from the record. Most of the software security can be installed from floppy disks, on which it is installed.

If you try to write down the data on a floppy disk, I will record the operating system on the computer screen. There can be a mother of a young viglyad, it’s a matter of fact that you must be able to write to a floppy disk.

For example, if you are using the COPY command or the XCOPY command of the MS-DOS operating system, you can write the file to the stolen floppy disk, so that the screen will appear as soon as possible:

Write protect error reading drive A
Abort, Retry, Fail?

Koristuvach is to blame, as the operating system is to blame for the situation. You can vibrate three types: Abort, Retry or Fail. For the whole it is enough to enter the first reverse symbol from the keyboard: Abort - , Retry - , Fail - ... You can vikoristovuvati yak headings so and little literi.

Vibir Abort or Fail means that the operating system is guilty of being able to read the information on the diskette (Abort simply skips the display of the operation, and Fail instructs the need to turn the program for the pardon code). If you need to see the operation, I will record, know from the floppy disk, save from the record and vibrate Retry.

It is necessary to respectfully put beforehand about trying to write to the stolen floppy disk. Reading files from a floppy disk, and launching a large program from it is not guilty of recording on it. Yaksho vi vpevneni, so writing to a floppy disk is not guilty, ale, vidbuvaetsya, great ymovirnit, that the computer is infected with a virus.

Deyak_viruy block the visnovok every now and then about trying the destructible I will write down, if I infect the visonuvany files, or the entangled sector of the floppy disk. Tse allow їm to become overpowered, as on the diskette of zagist installations. Tim doesn’t, you will reach the bazhany result, the floppy disk will become uninfected.

virus Plague.2647

Secure resident stealth virus. When an infected file is opened, it sees its own code, and then it gets infected again if the file is closed. In case of infected files on floppy disks, it is set to restore from the record. As soon as a zahist has been installed, the virus will not be able to infect files on a new one. Reveal the row "PLAGUE"

You can install the record on a floppy disk of any size - 3.5 inches and 5.25 inches. It is easy to use 3.5-inch floppy disks. It is enough for you to close the small hole in the cuff of the diskette with a special plastic crimp, as shown in fig. 2.1. It’s just as simple to make a note of this as it is: to reach the viewpoint.

Small. 2.1. I will write on a diskette with a size of 3.5 inches

To clean up a 5.25 "floppy disk, you need to glue the holes in the diskette envelope (Fig. 2.2). I can write it down, having seen the piece of paper you glued to the paper.

Often, know and install the user on a 5.25 "floppy disk. It is even more important that you can get into the floppy disk early and quickly. Therefore, if possible, you can view the diskettes with a size of 5.25" and replace them with 3.5 "diskettes.

Small. 2.2. I will write on a diskette with a size of 5.25 inches

Correct vibration of the computer locked order

The operating system can be locked up either from a hard disk or from a floppy disk. Zazvyay computer zavanazhutsya from the hard disk, at the moment when the computer is turned on, or rewrite it into drive A: a floppy disk is inserted (vipadkovo abnormally), locked up the operating system and thank you for it. If the floppy disk is infected with an enchanted virus, it will take control and immediately try to infect the hard disk of the computer.

Most computers allow the use of a priority, which is the fault of the security of the operating system. The order will be established behind the additional BIOS Setup programs. Read more about the BIOS Setup program in the "Updating file systems" section.

If you want to clean up the computer from a malignant infection with a corrupted virus, it seems that the operating system is guilty of locking up from the C: drive, and only, in any case, from the A: drive.

If you need to lock the computer from a floppy disk, you should be happy with it on these nemaє viruses. For a wide selection of anti-virus programs, for example, Doctor Web and Aidstest programs.

Well, if you prepare the system floppy disk for a long time, but you didn’t copy it, I’ll write it down. On the system floppy disk, you can write down programs for diagnostics of a computer - anti-virus programs, programs for reconverting the integrity of the file system and reference of the computer's hardware. How to insert the system diskette into the folder "Current system diskette".

unpopular come in

In organizations even more effective, it is possible to come in to the user, tied to the connections from the computers to the channels of the powerful and reliable viruses. In the first place, there are drives for flexible drives. The disk drive can be connected physically and knowingly from the computer, or it can only be connected to the CMOS memory, if you put a password on the BIOS Setup program.

In the ideal view of the computer, you need to turn on all drives, attachments for reading CDs, modems, last and parallel ports, blank adapters. It is very unrealistic, protesting will not be seen as such an idea.

Backup copy

It is even more important to organize backup copies of information so that it can be stored in computers. As a matter of fact, if you have a copy, you can make a copy of the hard disks of your computer, or copy only the information you need, as you cannot be updated by the other way.

For a backup copy, call up the magnetic lines. Recording on them is made possible by special digital recorders, called streamers. A lot of magnetic cassettes become from 200 MB to 4 GB. In the remaining hour, an attachment to a magneto-optical disk memory became available. According to the hopes and efficiency, the smell of the stench is significant to turn the magnetic line. A lot of magneto-optical disks are widely varied and range from tens of megabytes to decile gigabytes.

As long as you have no streamer or magneto-optical disk in your hands, then in the fall it will be possible to complete the simple floppy disks. Recording on floppy disks is the most important way of backing up. In a nutshell, diskettes can be as small as one megabyte. In other words, floppy disks are even worse. In some cases, they do not appear in respect of the previously recorded information.

One backup is not enough. We are guilty of the backup copy. The axle is a small butt. Vykonuete chergove copying and raptom to get out of harchuvannya or attack the virus. The computer hangs up, the data recorded in the computer and the copies appear to be copied

Viconuyuchi back up kop_yuvannya, we will protect the demand from the border. Be sure to double-check the integrity of the information you are copying before copying. Viconize the joke of viruses and rewiring of the file system. For a wide variety of applications, check out the selected versions of antivirus and programs such as ScanDisk. If you do not follow the rule, then all backup copies are early enough to be copied.

In especially widespread cases, display the cyclical copy of the tribute. For example, update one copy for a skin day, for a friend - for a day, a third - for a day.

archive files

You can use special floppy disks for backup copying, so before writing files to them, be sure to use archives. Archivator programs allow changing the size of the disk memory, borrowing files. Try to find out for a discussion of the overwhelming information, how to find it in the files.

Styles files can occupy significantly less space on disk, below the originals. So, text files, prepared, for example, in a text processor Microsoft Word for Windows, zvichy to change in vdvіchі. Zychayno, pratsyuvati with such a file is uncomfortable. Before the robot, you need to update for the additional help of the archivation programs.

In Danish hour the most popular archivators ARJ, PKZIP, RAR. All the stinks are about the same functions and can be used for making backup copies of documents.

More detailed information about the archived data is shown in the tenth volume of the "Library of the system programmer" series, which is called "Computer IBM PC / AT, MS-DOS and Windows. Nutrition and information". Infected only on the target butt of the ARJ archivator for the preparation of backup files. The format of the ARJ archivator's wikklik is folding:

ARJ<команда> [-<ключ> [-<ключ>...]] <имя архива>
[<имена файлов>...]

The first parameter is command - viznacha robotic mode of the archivator:

	Architect robot mode
	Adding new files to archives
	View files from archive
	Vityag files from archive
	Pereview in the place of the archive
	Transferring files to archives. Files will be written to the archive, and then the files will be seen from the disk
	Updating files in the same way due to the structure of directories and folders
	Updating files to archive. The structure of directories and subdirectories is not updated, all files from the archive are placed in one directory
	Update files in archive. Only changes and new files will be recorded before the archive. The files, which have been lost without a change, cannot be archived anew. For a rakhunok tsiogo happy for an hour

For one hover command, one can follow one or more optional additional parameters key... Enlargement of the mobility of the blame is seen by the symbol "-". Guided by the table of the most important additional parameters and descriptive characteristics:

additional parameter	appraisal
	Zachist the opened archive with a password
	Victory with the commands "a" or "m"
	The creation and updating of large-volume archives, roztashovanyh on decilkoh floppy disks. A skin diskette reveals one volume to an archive (file). If you want to modify the -v parameter: VV - type of sound signal between obrobkoy okremich volumes of archive; VA - automatically start a large space on a floppy disk (size of a book to that archive); Vnnnnn - size of archive volumes, for example V20000 - open archives from volumes of 20 KB; V360, V720, V1200, V1440 - open volumes, fixed size 360 ​​KB, 720 KB, 1.2 MB, 1.44 MB
	Update files from a single archive. Victory this parameter, as the update of files from the archive was interrupted by the archiver's announcements about the damage in the structure of the file-archive
X
	The archivator will NOT be able to supply the koristuvach with permission for the visitor of the latest projects, for example, for the opening of a new file of a large-volume archive, for the opening of catalogs

Send additional parameters to the archive file, followed by a list of video file names that can be added or seen. When specifying the names of the files, it is possible to use the symbols "?" i "*". If you don’t include the file_names list, then you’ll be mathing on all the files that are rooted in the stream catalog or archives.

Programs-archivators duzhe zruchny for storing backups on floppy disks. Since an archive file cannot be stored on a single diskette, the archiver allows you to open a large archive of files, but it can be stored from decile files. For a wider need to use an additional parameter V. Orema files of a large-volume archive can be written to a floppy disk.

There is a command to open a large volume of archives, from all files that have been moved in the stream catalog and all this from the catalogs, with the help of files, which may be the TMP or the extension of the BAK. Files of a large-volume archive size of a large size, at least 1.44 MB. You can record them on 3-inch floppy disks.

ARJ A -R -X * .BAK -XTMP. * -V1440! COLLAPS

Files of the opened archive matimut im'ya! COLLAPS and extended expansion:

COLLAPS.ARJ
! COLLAPS.A01
! COLLAPS.A02
! COLLAPS.A03
....

You can update files recorded in a large-volume archive, either by copying them to the hard disk of your computer, or without using floppy disks. For example, to update from floppy disks, use the following command:

ARJ X -V A: \! COLLAPS

Writing an update to the archive file will be fed to the archive file. Insert a floppy disk into the drive and press the button .

Making backup copies of documents in Windows 95

The Windows 95 operating system is handy for backing up documents and directories on a floppy disk. For a complete display of the My Computer pictogram and go to the directory, the files of which are required to be written to floppy disks.

Then move the mouse cursor over the pictogram of the file or the directory that is responsible for copying, and press the right button of the mis. A small menu appears on the screen.

Small. 2.3. Writing to the Library directory on a floppy disk

Select the Send To row from the menu, and then switch on the drive in the time menu to see a copy. On a little 2.3 mi, they showed how to copy the Library catalog on a 3.5-inch floppy disk.

If you plug in a floppy drive, you will be able to copy the copying process. As for copying all files in the directory of one floppy disk, there is a lack of evidence, the operating system will ask you to insert a floppy disk.

Unfortunately, our demonstration of vivantage is not allowed to copy files to floppy disks, size of which changes are made to the diskette itself. To copy it, in such a rank, it is too great to document it.

Perevirimo, chi nemaє viruses

To rewrite new programs, you will write them down to your computer, you need to check the anti-virus programs-polyphages of the last versions. Smell you can see whether it is a virus, seen at the time of the anti-virus program. Bazhano, what an anti-virus was victorious against you, the heuristic analysis of the program. It is possible, not to allow the emergence of new, yet not visible viruses.

The popularity of the anti-virus programs Aidstest and Doctor Web is great, but the smell is practically installed on the skin computer. In this way, at once, your computer will be reconfigured for the help of the program and will be able to survive in new viruses.

If you have a lot of newer versions of antivirus, speed up these programs, as you have є. Unimportant to those who will not be completely wrong, you will still allow a great number of viruses to emerge.

Poshuk viruses on a hard disk of a computer

On the cob all hard drives of the computer are converted by the Aidstest program. Enter the command in the system requested DOS.

Dearly quest for the occasion, so that the program will be seen before the hour of the computer's revision. As soon as the virus is detected, Aidstest will tell you about it.

Bagato virusi, which does not appear in Aidstest, can be used in the Doctor Web program. In addition, Doctor Web allows you to visually analyze the programs of the inviting sectors. To repeat the revision behind Doctor Web's help.

DRWEB * / CL / HI / AR / HA1 / RV / UP

Anti-virus Doctor Web will revise all hard drives of a computer, at the same time the virus doesn’t just pop-up in the archived files, but in the archive files, as well as in the archived files. As soon as the virus will appear, the program will appear on the screen as soon as possible.

At all butts, aimed at a whole lot of razdilі, there will be only a shout of viruses, but there will be no vision of the evolved viruses. For any need, run the anti-virus program again once, having logged in from the system diskette.

Poshuk viruses on floppy disks

All new floppy disks, as well as floppy disks that were given to someone else, must be reconverted for virus infection. For the sake of vicorizing the anti-virus polyphages Aidstest and Doctor Web. Lastly, wipe with one chat, and then with programs. The offensive butt shows how to change the floppy disk inserted into the A: drive.

AIDSTEST A: / B
DRWEB A: / CL / AR / HA1 / UP / NM / OF

Viruses in archive files

There is a large amount of space on a hard disk and floppy disks, a lot of files can be archived. For all, you can choose special programs-archivators to change the size of the files for the rakhunok usunennya overmirnosti danikh, recorded in the file. If you know you need a file from the archive, I know the program-archiver.

Files in the middle of the archive are stored in a single viewer, so that you can joke a virus by its signatures. If you have recorded an infected program in the archives, you may become uncomfortable for anti-virus software.

Deyakі anti-virus programs, for example Doctor Web, allow you to reverse the files recorded in all the middle archives. Revise archives, Doctor Web will revisit the entries in the new file hourly and lastly.

As soon as you have seen viruses in your computer, you will need to overwrite all the files of the archives, if your anti-virus program is not able to work with the archives. Update files from your archives on disk independently, and then rewire your antivirus software

Speak, if on one computer there is a good decal for a cholovik, the stench of vikoristovuyut rizni so that you can get access to hard disks. For example, the Diskreet application with the Norton Utilities package, allowing you to create a decal of logical drives. Skin caretakers can only have access to discs that are otherwise unavailable for them.

virus ArjVirus

A secure non-resident virus. There was a glitch in the streaming catalog and in the catalogs of files in archives opened by the ARJ archiving program. Archive files of viruses updated only by extension - ARJ.

If the file is an archive of events, the virus will open the file, which can be stored from the symbols from "A" to "V", with extended COM. The virus will write 5 Kbytes to its code and in the end it will add additional bytes.

We use the virus wiklica program-archivator ARJ, you are welcomed, you will be able to install them in one of the catalogs, re-sponsored by the change PATH. For tsyogo vikoristovє

C: \ COMMAND.COM / C ARJ A

The value of the ArjFile parameter contains the name of the file-archive known by the virus. The ComFile parameter reveals the name of the newly opened file to the virus. This is the command to add a new file-archive to a virus detection of a new virus file. Then the virus can see the output file.

If you don’t show the information on the screen, you’ll want to appear by the ARJ program-archiver, the virus time-consumingly includes all the files on the monitor’s screen.

The main idea of ​​a virus polyag is that, having updated files from an infected archive, the file can be updated to a new one.

It is necessary to check the viruses on all disks. The best way to get rid of it will be koristuvach, which has access to all disks of the computer. In the case of a skin problem, Koristuvach is guilty of overturning the discs available to him. It’s just that there’s some kind of koristuvachіv to appear, but on a disk available to you, the presence of a virus, guilt is absolutely guilty of all the corystuvachi of the computer.

Yaksho vi viyavili virus

The greatest value is to represent your data recorded in a computer. There can be texts of documents, files of electronic tables, databases, source texts of the program, etc.

Whether the program is secured by viruses, it is possible to update from distributions or backups. And the axis with the data on the right is denoted better. As long as the dans were never copied, the stench might be irrevocably consumed.

If you vius, in the first place you need to re-enroll from a blank floppy disk and copy your data from the hard disk of your computer to floppy disks, magnetic lines, for example, if you want to add information. You can only start playing until the computer is running.

As soon as the virus appears, then it is possible, the wine has already been saved in the computer information. Ruinuvannya can be of a growing character. You can, the files with the data will be degraded and you cannot read it, but you can’t read the stench slightly, and you can’t see it all at once.

virus Rogue. 1208

Non-secure resident virus. I know files from DBF extensions, write in them the first byte "R" and vibrate the logical operation in place of the file with the number 13, until the first character, which code is 13. I know the files CHKLIST ???. In the month, if the sum is meaningful to the rock and the meaning of the month is dated 2000, the virus will display the text: "Now you got a real virus! I" m the ROGUE ...! "

Try to z'yasuvati, which is the virus itself, having drunk before you in the computer and how to rob you. You can edit some information from the virus descriptions, which can be supplied at once with the anti-virus programs. In fact, all anti-virus programs may have such lists. The stench can be found in a snazzy text file, or at a viglyad of special hypertext databases.

As soon as the virus was detected in the computer, it was already immediately that the virus got wider, having infected the computers in your organization. Їх needs to be revised in a general order. Bagato koristuvach_v this year may have computers in his home. The stench can also show up infected.

It is necessary to reconsider all the floppy disks that were installed for robots because of infected computers. The stench can be found infected with intrusive and file viruses. Virus can take care of them, and then infect the computer again. Floppy disks infected with viruses, require vilikuvati or vidformatuvati.

Yak likuvati computer

In order to do this, you have tried to copy all your data (documents, source texts, database files) from your computer, it's time to fix your computer and see if your virus has become infected. For you, there are three ways to see the virus from a computer.

The simplest of them is a pole in the change of all software security installed in the computer. You will be guilty of reinstalling the operating system and all programs again. If a virus has infected a zapped-up record, then it is possible to update it by formatting the logical disks of the computer, speeding up for it using the FORMAT command. However, you can not see the formatting virus from the head of the hard disk. For a long time, you can quickly use the FDISK command with the undocumented / MBR parameter, and then you can install it on the hard disk and split logical disks.

Such operations, like formatting a logical disk, seen by a partition of a logical disk using the FDISK command, will increase all files on this disk. In front of that, the files are not very necessary.

In order to re-install the partition and logical disks on the hard disk and format them, you can start before installing the operating system and other programs. Outside the installation of software security of the computer, it takes an hour. To speed up the process, if possible, install software products not from floppy disks, but from CDs.

You can signify the update of the original computer, as soon as you will be able to back up all the information recorded in the computer. In general, when logging and formatting logical disks, you can update the program from the backup copies. As soon as you will be able to see the update, you will be storing it up, so that you will be able to use it when you set up backup copies.

Another possibility of transferring manually the visibility of viruses and updating of the nursery sectors and files. The whole method is the most folding and high quality. We provide information about the manual update of the computer in the section "Manual update of the operating system".

I, nareshty, remains the possibility of transferring special anti-tier programs. Anti-virus programs are able to detect and see viruses, which made the computer newer. It's a pity that the update is not necessary either, because the larger category of viruses is irreversible because of the programs and data recorded on the disks of the computer. In any case, it is necessary to re-establish the security program.

It infects the computer in a very short time with the anti-virus polyphagous programs Aidstest and Doctor Web. More reports on the tsі and іnshі programs, scho allow you to see viruses from the computer, read in the offensive section, as it is called "Krashiy zasib".

Likuvannya computer anti-virus programs

There are a number of resident viruses in the memory of the computer, overcoming the successful strategy of infected programs and enticing sectors. That is why it is bazed to vikonuvati lіkuvannya only when the computer is locked from the system diskette, vіnоvіd vіrusіv. On a floppy disk, in front of the front, you need to write down anti-virus programs-polyphages, for example Aidstest and Doctor Web.

The Aidstest program allows you to see the detected virus. To do this, run Aidstest with the / F parameter:

Deyaki viruses cannot be detected and used with the Aidstest program, so you need to be victorious in spite of the Doctor Web antivirus:

DRWEB * / CL / UP / CU

With Aidstest and Doctor Web you can use not only hard drives, but also floppy disks. To change the parameter *, which means the robot uses hard disks of the computer, you need to use a drive:

AIDSTEST A: / F
DRWEB A: / CL / UP / CU

scan

Anti-Virus Zahist.

The main way to fight bully viruses is to use anti-virus programs. You can vikoristovuvati anti-virus programs (anti-viruses), do not be aware of those like the stink of the virus. However, without the reasonable principles of organizing anti-viruses, knowing the types of viruses, as well as the methods of their expansion, it is impossible to organize a reliable computer hijacker. As a result, the computer can be infected, if antivirus is installed on the new one.

A few of the fundamental methods of revealing that to the origin of the viruses:

· Scanuvannya;

· Euristic analysis;

· Vikoristannya anti-virus monitors;

· Viyavlennya zmin;

· Vikoristannya anti-virus, installed in the BIOS of the computer.

In addition, practically all anti-virus programs will automatically update infected programs and entangled sectors. Squeaky and pricey.

The simplest technique is that the anti-virus program looks at the files after the first glances into the joke of the signatures of the viruses. Given the signature, the unique nature of the electronic data should be recognized, so that the virus can be detected, and not be used in other programs.

Anti-virus scanners let you know only if there are any viruses, for which a signature is assigned. Zasosuvannya simple program-scanners does not hijack Your computer from the penetration of new viruses.

In order to encrypt polymorphic viruses that have changed their code when they are infected with new programs, or the enchanting sector, it is hard to see the signature. Because of this, anti-virus scanners cannot detect polymorphic viruses.

Heuristic analysis allows to detect earlier unavailable viruses, moreover, it is not necessary to collect data about the file system in advance, which is, for example, looking at the lower method of detecting changes.

Anti-virus programs that implement the method of heuristic analysis, rewrite the programs and enchant sectors of disks and floppy disks, add the code characteristic of viruses to them. The heuristic analyzer can be used, for example, when the program is being revised, it will install the resident module in the memory, or write down the data in the created program file.

Practically all modern anti-virus programs implement the most powerful methods of heuristic analysis. In fig. 1 we showed one of these programs - a McAffee VirusScan scanner, launched manually for anti-virus disk rewiring.

If the antivirus detects infections in the file, let it be added to the monitor screen and to prevent the entry from the system log. Regardlessly, the anti-virus can also be used to direct any manifestations of the virus of the fenestration administrator.

As well as possible, anti-virus file, new version. Only one possibility is displayed in the last vipad - to see the infection file and then update it from the backup copy (as a matter of fact, you have it).

Qia article about those anti-virus software secured. For storing heuristics in the assessment of usability, see the heuristic assessment.

euristic analysis It is a method of using computer anti-virus programs for detecting previously unidentified computer viruses, as well as new options for viruses already in “wild nature”.

Heuristic analysis є on the basis of expert analysis, which is the reason for the cleanliness of the system to particular contamination / risk according to the rules of the new rules. Analysis Bagatocritical (MCA), є one of the most important. The whole method is derived from statistical analysis, which spirals on obvious data / statistics.

operation

Bіlshіst antivіrusnih programs, SSMSC vikoristovuyut evristichny analіz vikonannya tsієї funktsії, vikonavshi Team programuvannya of sumnіvnoyu prog abo stsenarіyu in spetsіalіzovanіy vіrtualnіy mashinі, team itself dozvolyayuchi antivіrusnu programa vnutrіshno іmіtuvati those scho steel used, Yakscho pіdozrіly file povinnі boule Buti Realized at zberezhennі pіdozrіly code visions from a real car light. Then the command can be analyzed, as it stinks, the monitoring of wider external calls, such as replication, the file is overwritten and rewritten, when the file is detected. It’s just one, or a little bit of viruses, because it’s going to be detected, the file of meanings is because it’s potential virus, and it’s on the alert.

The second extension is a method of heuristic analysis for antivirus programs, to decompile the program, and then to analyze the machine code, so that all the middle ones can be found. The output code for a given file is matched with the output code for the output of the virus and virus-like behavior. How to read the output from the output code, read the code from the output of the virus or the virus, because of the meaning, the file of values, and alertness.

efficiency

Heuristic analysis allows for the detection of a lot of viruses earlier than unavailable viruses and new versions of current viruses. Protest, heuristic analysis of pratsyuє on the basis of admission (change the file with the code and function of the view of the viruses). Tse means, well, better for everything, skip new viruses, as robots didn’t know any of the new viruses before. Otzhe, the efficiency to achieve low accuracy and number of gracious spratsovan.

Oskіlki new viruses appear as human precursors, information about them is provided by the heuristic analysis of the dvigun, and by themselves the dvigun is saved for the emergence of new viruses.

So also a heuristic analysis?

Euristic analysis is a method of revealing viruses by way of analysis to the code of suspicious authorities.

The traditional methods of detecting viruses involve the detection of high-profile programs by the correct code in the program with the code of all types of viruses, which were also included, analyzed and recorded in the database of the history.

At that hour, the method of signature detection is still being developed, and the method of signature detection is also becoming more common, in conjunction with the development of new threats, as they vibrated at the turn of the table and continue for the whole hour.

For the solution of the problem, the Heuristic model of the bullet is specially broken up, so that it appears that there are signs that it can be known in the new home, new viruses and modified versions of different threats, as well as in the programs of various households.

Cyberzlochintsi steadily break up new threats, and heuristic analysis є one of the non-common methods, victorious for dealing with the magnificent team of new threats, they were busy today.

Heuristic analysis is also one of the non-basic methods, the old fight against polymorphic viruses - a term for a quick code, which is constantly changing and adapting. Heuristic analysis is included in the advanced security solutions, promoted by such companies, such as Kaspersky Labs, to detect new contaminants, to avoid the smell of creating a shkodi, without the need for a specific signature.

Yaka Euristic analysis of the robot?

Heuristic analysis allows victorious methods to be used. One heuristic method, vidomy as a static heuristic analysis, includes decompilation of programs and viewing its output code. The whole code is to compare with viruses, which are already seen and found in the Heuristic databases. As a result of the entry code, the code is written from the database of the Heuristic, the code of meanings as a potential threat.

The first method of visualization yak dynamic heuristics. If you want to be able to analyze it as you grow older, you don’t suck people, you’ll smell the words in a controlled environment, like stolen laboratory and vip testing. The whole process is analogous for the heuristic analysis - ale and in a virtual light.

Wonderful if the program is okay with the code in the middle of the specialized virtual machine - or the driver - and yes the anti-virus program has a chance to revise the code and simulate it, so that it will be possible to correct the file. I will look at the skin team, like a spratsovuє, and a sound, be it self-made, overwrite files, as well as іnshі projects, which are outlandish for viruses. potential problems

Heuristic analysis It is ideal for detecting new threats, albeit, for being effective;
