Antivirus Zaitseva (Z-Oleg.com developer site), or AVZ program, is focused on a qualified user. It contains means to determine the virus that is not in the antivirus database. It turns out that many antiviruses will not cope with those viruses that allows AVZ to neutralize.

Zaitsev Anti-Virus is more oriented on network viruses And allows you to remove trojans that cannot be removed by other antiviruses. In some cases, this utility is more useful than Kaspersky Anti-Virus. By the way, it can be said that KAV and AVZ relatives. The AVZ program developed Oleg Zaitsev, but later she was redeemed by Kaspersky Lab, although Zaitsev continues to develop it and maintain it, and some AVZ solutions moved to KIS.

Let's figure out what is interesting AVZ utility? First of all, AVZ, in contrast to other antiviruses, can be launched in safe modeNamely in safe mode the easiest way to track the virus.

Also, in contrast to most antiviruses, AVZ does not require installation. The utility can run from a flash drive and in safe mode, which generally makes AVZ an indispensable scanner.

But this is not all AVZ functions. Although AVZ has an heuristic analyzer, allowing to determine the malware without using any antivirus base, the antivirus base of AVZ is. And it is quite large and often updated. In addition, AVZ has a base of safe files. This base contains a digital signature of a huge number. system files and safe processes. If a digital signature of some kind of process differs from the signature in the database, the file has been changed (perhaps with the virus).

Built-in dispatcher (command service \u003d\u003e Process Manager) Processes uses the secure file database when the processes list is output. If the process name is displayed in red, the process executable file has been changed. Perhaps "tried" the virus. And perhaps the process was simply updated by the system. Try to update the databases first (command file \u003d\u003e update the databases), and then open the processes Manager again - if the process is again "red", probably it has been changed by the virus.

Using the Tools command \u003d\u003e Check the Safety File Base File, you can check the selected file. The program also allows you to check the Microsoft security directory file: To do this, use the service command \u003d\u003e Check the authenticity of the Microsoft security directory.

AVZ antivirus perfectly copes with the detection of rootkits. Ruckit is a program or a set of programs for hiding traces of an attacker or a malware in the system. AVZ can not only find, but also block rootkits. True, there are restrictions. The program can block rootkits operating in user mode, and can only detect rootkits operating in kernel mode. While the program is able to detect the rootkits of the kernel level in the following operating systems: Windows NT, Windows 2000 Pro / Server, XP, XP SP1, XP SP2, Windows 2003 Server, Windows 2003 Server SP1 (information from the developer's website, z-oleg.com/secur/avz/).

A heuristic analyzer deserves special attention, which allows you to identify viruses and malware on indirect features using the file system analysis, registry and monitoring of the program's actions. If you want to use the analyzer, turn on the heuristic check switch on the Search Area tab.

Built-in processes, services and drivers allows you to get information about running processes, services and downloaded drivers. This is a purely information utility. As already noted, this dispatcher is associated with the database of safe files. All unsafe processes will be marked in red in the dispatcher list. To start only the Process Manager, select Tools Tools \u003d\u003e Process Manager, and to start the service manager and drivers - Service Manager \u003d\u003e Service Manager and Drivers.

The AVZ program contains a neuroperator that allows you to detect the virus using neural network. The neuro-analyzer is successfully used to detect keyboard spies And Trojan Libraries (and these programs can be used to intercepted everything that Introduced the user from the keyboard and transmit this information to a third party - an attacker). You can start the Trojan Library Detector using the Tools command \u003d\u003e Manager of embedded DLL.

Like any other antivirus, Avz is able to place suspicious objects in quarantine - this is a special hard disk catatog. To avz placed suspicious objects in quarantine, you need to check the box Copy suspicious objects to quarantine on the Search Area tab. And view objects that this moment Located in quarantine, you can command the file \u003d\u003e View quarantine.

    For novice users, there will certainly be two masters:
  • master of the search and troubleshooting problems - allows you to find problems in the system configuration, is called by the file command \u003d\u003e Search and troubleshooting the problem;
  • winSock SPI / LSP Analyzer Settings - analyzes possible errors in the WinSOCK SPI / LSP settings settings, called the Tools command \u003d\u003e WinSock SPI manager.

Among other things, AVZ allows you to view the open TCP / UDP ports. You can do it using the Tools menu command \u003d\u003e Open ports TCP / UDP. An open port analyzer uses the base port base, which is commonly used by Trojans and other malicious programs. The analyzer will also help find suspicious ports that are not in the base of known ports.

AVZGUARD system is used to combat viruses that are very difficult to detect. Avzguard can block access to the critical system objects and protect it from the virus. True, working with Avzguard's protection included is completely uncomfortable. You can enable and disable protection using the AvzGuard menu commands.

Avz functions have a lot, and, it is clear, we all will not consider.

    We mention several functions worthy of attention:
  • Extended utilities for searching for disk files and to search in the registry. Called commands service \u003d\u003e Search files on disk and service \u003d\u003e Search for data in the registry, respectively. When searching for disk files, it is possible to eliminate secure files, and the files that are labeled as unsafe can be placed in quarantine for analysis. The data search utility in the registry can "see" the registry keys, "masked" by rootkit, i.e. Keys hidden by a malicious program from the user.
  • The program is able to check and treat NTFS-flows, and this is able to do far from all full antiviruses.
  • BootCleaner cleaner, allowing to delete malicious files, Drivers, Services and registry keys.
  • The program can get direct access to the disk to access locked other processes files. The direct access to the disk works with file Systems FAT (16/32) and NTFS.
  • The Advanced Monitoring Driver AVZPM (AVZPM \u003d\u003e command to install the advanced process monitoring driver), used to start and stop processes, as well as for downloading and unloading drivers.
  • Support for ZIP, RAR, CAB, GZIP, MHT, CHM format archives, as well as support for postal formats.
  • The analyzer is loaded software files, Start which can be commanded by the service \u003d\u003e Downloaded Program Files Manager.

As it was already noted earlier, after loading the archive with the program, simply unpack it on hDD And select the file file \u003d\u003e Update the databases. It is clear that the connection to the Internet should be actively - then the anti-virus programs of the program will be updated. Then click on the Start button to start scanning the system.

AVZ is an efficient and popular antivirus program among users. AVZ is wide functionalitywhich allow you to detect and subsequently neutralize various dangerous elements. These include viruses, postal and network worms, rootkits, trojans and the like. The appendix contains a huge number of important means to ensure guaranteed protection against viruses. You must also note the database of secure updated files.

Purpose of free antivirus utility AVZ

The main purpose of the AVZ anti-virus utility lies in detection and removal:

DIALER (Trojan.dialer).

Adware and Spyware modules.

Trojan programs.

Postal and network worms.

Backdoor modules.

Trojandropper, TrojandownLoader, Trojanspy.

Key Features

Firmware providing heuristic system check. Firmware action based on search famous viruses And Spyware on the available indirect features - on the basis of the analysis of files, the registry in memory and on the disk.

Updated system and secure file base. IN this base Included digital signatures of thousands of secure processes and system files. The base is connected to each of the AVZ anti-virus utility systems, and its operation is carried out according to the "own / alien" principle - making secure files to quarantine is not provided, for them the output of warnings and deletion, the base is used by anti-troops, various analyzers, file search system. Built-in processes manager, in particular, selects secure services and processes with a certain color, and the search for files can use the exception of known files from the search (which is very important and useful when performing the search for Trojan programs on the disk).

Built-in Rootkit System. RootKit detection is carried out on the basis of the study of the main system libraries on the possibility of intercepting their functions without the use of signatures. The anti-virus utility is capable of detecting not only Rootkit, but also to correctly block the actions of the UserMode Rootkit in its process, as well as Kernelmode Rootkit in the system level. RootKit countering function is available in all AVZ service functions, the AVZ scanner as a result is able to detect disguised processes, and in the registry, the search system easily finds the masked keys and the like.

Anti-Court is equipped with an analyzer that performs the search for services and processes where Rootkit is masked. One of the main features The Rootkit Counterting Utility AVZ systems lies in its performance in Win9x (many rootkits work in Win9X systems, intercepting the API functions to mask themselves). Next feature avz will universal system Kernelmode Rootkit locked and blocking.

Keyboard Spy Detector and Trojan DLL. The search for Trojan DLL, as well as keyboard spies Keylogger, is performed without using the signature base based on the system analysis, which allows you to quite confidently detect previously unknown Keylogger and Trojan DLL.

Neuroenalyzer. AVZ For Windows, in addition to the signature analyzer, includes a neuromemologist, which can perform suspicious files through a neural network. To date, neuralitis is effectively used in the keylogger detector.

WinSock SPI / LSP Retail Analyzer. The WINSOCK built-in analyzer makes it possible to analyze the settings, diagnose possible errors In the setting, and then make automatic treatment. The presence of automatic diagnostics and subsequent treatment will be extremely useful for beginners and inexperienced users (there is no automatic treatment in LSPFIX programs). For the study manually SPI / LSP in the utility operates a specialized LSP / SPI settings manager. And on WinSock, the action of anti-troops is performed, which stops the operation of a malicious code.

Built-in service dispatcher, processes and drivers. The built-in dispatcher is designed to explore downloaded libraries, running processes, Drivers and services. The operation of the processes dispatcher also spreads the action of anti-troops (as a result, it can "see" the processes that are masked by rootkit). Process Manager has a close relationship with the Safe File Base of the AVZ utility, recognized system and secure files are highlighted in a special color;

Built-in utility, providing file search on disk. This utility Allows you to search for files to a variety of criteria, while the way the search system is an order of magnitude higher than the system search capabilities. Anti-Court applies to the search system, thanks to which the search quickly detects files masked by rootkit, and can delete them. At the same time, files identified as safe, can be filtered using a filter that eliminates these files from search results. Search results can be accessible as a table or as a text protocol where you can mark the files for the room in quarantine or subsequent removal.

Built-in utility for finding data in the registry. This utility allows you to search for parameters and keys according to a specified sample, the results obtained will be available as a table or as a text protocol, where you can note the key group immediately to remove or export. Anti-sews quickly detects files masked by rootkit, and can easily remove them.

Open Port Analyzer TCP / UDP. It is also protected by anti-troops in windows system XP is even displayed for each port the process that uses it. The analyzer is based on a timely updated database of ports of well-known system services and Trojan / Backdoor programs. The search for ports of the Trojan pest is included in the basic system verification algorithm - if suspicious ports are detected, the protocol indicates a warning indicating which Trojan programs are able to use this port with sled targets.

Network sessions analyzer common resources open files On the network. Its work is carried out in NT / W2K / XP and Win9x.

DPF Analyzer (Downloaded Program Files) - Displays DPF elements, has a connection to AVZ systems.

Heuristic deletion of files. If this option is enabled and the hazardous files were deleted during treatment, the system is automatically study, which includes IE extensions, classes, Bho, WinLogon, autorun types, and the like. The detected links to the dangerous file are cleaned, and this is noted in the protocol. For cleaning, firmware of system treatment are actively used.

System recovery firmware. They perform recovery of program start settings, Internet Explorer. and other parameters damaged by malicious programs. You can manually run recovery, the user specifies the parameters restored.

Check archives. From version 3.60 AVZ, archives and components are checked. Tar, Gzip, Rar, Zip format archives are being checked; MHT files and letters email Chm; archives.

Control scripts. The administrator can write a script that will perform a set of specified operations on the user's PC. Such scripts are convenient to use in the corporate network.

Check and Treatment of NTFS Flow.

Process analyzer. Applies microprograms of analysis and neural networks. Applied with an extended analysis, designed to find suspicious processes in memory.

Avzguard feature. Provides a struggle with difficult hazardous programs, can also protect applications that the user will indicate.

Driver Boot Cleaner. Used to clean the system (registry keys, drivers, files) from Kernelmode.

Process Monitoring Driver, as well as AVZPM Drivers. Used to track start, load / unload drivers, stopping processes to find masking drivers and find changes in drivers structures that create DKOM rootkits.

Direct Access Function for Work with Blocked Files. Allows the scanner to analyze blocked files and send them to quarantine.

AVZ - small free program To remove spyware and advertising software. This application Equipped with scanning functions and automatic detection of potential threats.

Changes in Anti-virus utility AVZ 4.46 (02.29.2016):

  • Modifications and modifications for compatibility with Windows 10

AVZ is a free antivirus utility, first of all intended to detect and remove Spyware and Adware programs and modules, as well as rootkits, network and postal worms, various Trojan programs (including all their types, in particular Trojan-PSW, Trojan-Downloader, Trojan-Spy), Trojan Zlonil Programs (Dialer, Trojan.dialer, Porn-Dialer), Backdoor (programs for secretive remote control PC), keyboard spies and other malware.

AVZ is a direct analogue of programs such as Trojanhunter and Lavasoft AD-Aware 6, but largely surpasses them, combining the capabilities of each of them, and surpassing these products in functionality.

The program was developed by the Russian programmer Oleg Zaitsev ("Kaspersky Lab"). Antivirus AVZ does not require installation and is a truly universal means to fight, both with Spyware and Adware, and with Troyan, and Backdoor programs.

Systematic computer checks using the AVZ utility perfectly complement installed antivirus In the system (, etc.), as many viruses and worms can easily bypass the protection of popular antiviruses and output them.

Also antivirus programs Spyware and AdWare class programs can be missed, which is due to the difficulties of classification and identify such programs from popular antivirus solutions. It should be noted that programs classifying as Spyware, Adware are essentially viruses or trojans. The purpose of such software is to collect data or implement the user with spyware modules exclusively in marketing purposes (the information collected does not contain important data: logins and passwords, credit card numbers, etc., and downloadable information is advertising or updates). In any case, the purpose of Spyware and Adware programs is targeted advertising, and here such a utility, as AVZ will be extremely necessary.

The program does not require installation, download last version AVZ can be referenced below. The AVZ program interface in Russian, navigating the program is simple and quite convenient. The main program window contains all the basic controls - the main menu, the settings of the search and treatment process, the protocol viewing window and the status bar.

During the check, most of the AVZ interface elements will not be available.

Please note that before getting started with aVZ program (Check / Treatment) It is recommended to disable the background monitoring of registry changes and anti-virus monitors. This is not necessary to do - it is possible not to turn off, but the check speed can in this case can significantly increase (up to several hours, instead of minutes) due to the fact that, due to its specifics, the anti-virus monitor will need an additional time for checking the files opened (new files Checked at the time of opening them).

In case there are problems with automatic update Bases You can download the archive containing the actual base - download the archive with the base (updated twice a day).

Download AVZ for free, without registration.
