AVZ is a free anti-virus application for a computer running Windows was created by a Russian, our compatriot Oleg Zaitsev.

Download AVZ free tool to protect your computer from many different threats, viruses and more. The antivirus will give you the opportunity to use your own scripts, this advantage administrators of corporate networks will appreciate the most. Based on all of the above, we can confidently say that AVZ will be an excellent shield for your system.

You can download AVZ for free from the official website and the latest version, there is also an archive with anti-virus databases updated once a day.

History is silent about what prompted him to create the AVZ utility, but his creation is still a good success to this day. The author of the program wanted to create something universal, because, as you know, from year to year, hackers try to come up with new bypasses of anti-virus programs, so Oleg tried to develop a new detection algorithm, namely, to create a utility that will detect a virus application by other signs than others similar programs.

Therefore, AVZ can detect malware not only by its identity in signature databases, but also by characteristic file modifications and other changes in the registry. The utility has everything you need to find and remove viruses - its list includes a scanner, the ability to send suspicious files to quarantine, support for heuristic analysis.

However, it is better to use the application as an assistant to the main anti-virus package, since popular anti-viruses like NOD32 or Kaspersky Anti-Virus update their anti-virus databases almost every day, which means that very reliable protection will be guaranteed from this side. In turn, AVZ will back up the main antivirus and catch viruses that managed to bypass identification by signatures. The program developer himself claims that his creation is focused on the disposal of Trojans and utilities for remote monitoring of a PC, so the utility will not return to normal operation infected files.

There are universal programs like a Swiss knife. The hero of my article is just such a "universal". His name is AVZ(Antivirus Zaitsev). With the help of this free You can catch antivirus and viruses, and optimize the system, and fix problems.

AVZ Features

I already talked about the fact that this is an antivirus program in. The work of AVZ as a one-time antivirus (more precisely, an anti-rootkit) is well described in its help, but I will show you the other side of the program: checking and restoring settings.

What can be "fixed" with AVZ:

Repair startup programs (.exe, .com, .pif files)
Reset Internet Explorer settings to default
Restore Desktop Settings
Remove rights restrictions (for example, if a virus blocked the launch of programs)
Remove banner or window that appears before login
Remove viruses that can run with any program
Unblock Task Manager and Registry Editor (if the virus has prevented them from running)
Clear File
Disable autorun programs from flash drives and disks
Delete junk files from hard drive
Fix desktop issues
And much more

It can also be used to check the safety of Windows settings (in order to better protect against viruses), as well as optimize the system by cleaning startup.

The AVZ download page is at .

The program is free.

First, let's protect our Windows from careless actions

The AVZ program has very many functions affecting the operation of Windows. it dangerous, because in case of an error, trouble can happen. Please read the text and help carefully before doing anything. The author of the article is not responsible for your actions.

In order to be able to "return everything as it was" after careless work with AVZ, I wrote this chapter.

This is a mandatory step, in fact, creating a "retreat" in case of careless actions - thanks to the restore point, it will be possible to restore the settings, the Windows registry to an earlier state.

Windows Recovery is a required component of all versions of Windows, starting with Windows ME. It is a pity that they usually do not remember about it and waste time reinstalling Windows and programs, although it was possible to just click a couple of times with the mouse and avoid all problems.

If the damage is serious (for example, some system files have been deleted), then System Restore will not help. In other cases - if you configured Windows incorrectly, "tricked" with the registry, installed a program from which Windows does not boot, incorrectly used the AVZ program - "System Restore" should help.

After work, AVZ creates subfolders with backups in its folder:

/backup- backup copies of the registry are stored there.

/Infected- copies of removed viruses.

/quarantine- copies of suspicious files.

If problems started after AVZ was running (for example, you thoughtlessly used the AVZ System Restore tool and the Internet stopped working) and Windows System Restore did not roll back the changes made, you can open registry backups from the folder backup.

How to create a restore point

Let's go to Start - Control Panel - System - System Protection:

Click "System Protection" in the "System" window.

Click the "Create" button.

The process of creating a restore point can take up to ten minutes. Then a window will appear:

The restore point will be created. By the way, they are automatically created when you install programs and drivers, but not always. Therefore, before dangerous actions (setting up, cleaning the system), it is better to once again create a restore point in order to praise yourself for foresight in case of trouble.

How to restore your computer using a restore point

There are two options for launching System Restore - from under running Windows and using the installation disc.

Option 1 - if Windows starts

Let's go to Start - All Programs - Accessories - System Tools - System Restore:

will start Choose a different restore point and press Further. A list of restore points will open. Choose the one you need:

The computer will automatically restart. After downloading, all settings, its registry and some important files will be restored.

Option 2 - If Windows won't boot

You need an "installation" disk with Windows 7 or Windows 8. Where to get it (or download), I wrote in.

We boot from the disk (how to boot from boot disks, it is written) and select:

Select "System Restore" instead Windows installation

Repairing the system after viruses or inept actions with the computer

Before all actions, get rid of viruses, for example, using. Otherwise, there will be no sense - the corrected settings will be "broken" by the running virus again.

Restarting Programs

If a virus has blocked the launch of any programs, then AVZ will help you. Of course, you also need to start AVZ itself, but it's pretty easy:

First we go to Control Panel- set any type of view, except for Category - Folders settings - View- uncheck Hide extensions for registered file types - OK. Now each file has extension- a few characters after the last dot in the name. Programs usually .exe and .com. To run AVZ antivirus on a computer where programs are prohibited, rename the extension to cmd or pif:

Then AVZ will start. Then in the program window itself, press File - :

Points to be noted:

1. Restore launch options.exe, .com, .pif files(actually solves the problem of running programs)

6. Remove all Policies (restrictions) of the current user(in some rare cases, this item also helps to solve the problem of starting programs if the virus is very harmful)

9. Removing system process debuggers(it is highly desirable to note this item, because even if you checked the system with an antivirus, something could remain from the virus. It also helps if the Desktop does not appear at system startup)

, confirm the action, a window appears with the text "System Restore Completed". After that, it remains to restart the computer - the problem with starting programs will be solved!

Desktop startup recovery

Enough common problem- Desktop does not appear at system startup.

Run Desktop you can do this: press Ctrl + Alt + Del, launch the Task Manager, there we press File - New Task (Run...) - enter explorer.exe:

OK- The desktop will start. But this is only a temporary solution to the problem - the next time you turn on the computer, you will have to repeat everything again.

In order not to do this every time, you need to restore the program launch key explorer("Explorer", which is responsible for the standard viewing of the contents of folders and the work of the Desktop). In AVZ we press File- and mark the item

Perform marked operations, confirm the action, press OK. Now when you start the computer, the desktop will start normally.

Unlock Task Manager and Registry Editor

If the virus has blocked the launch of the two above-mentioned programs, the ban can be removed through the AVZ program window. Just check two things:

11. Unlock Task Manager

17. Unlock Registry Editor

And press Perform the marked operations.

Problems with the Internet (Vkontakte, Odnoklassniki and antivirus sites do not open)

This component can check four categories of problems with different degrees of severity (each degree differs in the number of settings):

System problems- this includes security settings. By ticking the found items and clicking the button Fix flagged issues, some loopholes for viruses will be blocked. There is also a reverse side of the coin - increasing safety, reducing comfort. For example, if you disable autorun from removable media and CD-ROMs, when inserting flash drives and disks, a window with a choice of actions will not appear (view the contents, start the player, etc.) - you will have to open the Computer window and start viewing the contents of the disk manually. That is, viruses will not start automatically, and a convenient hint will not appear. Depending on the Windows settings, everyone will see their own list of system vulnerabilities here.

Browser settings and tweaks- Internet Explorer security settings are checked. As far as I know, the settings of other browsers ( Google Chrome, Opera, Mozilla Firefox and others) are not checked. Even if you do not use Internet Explorer to surf the Internet, I advise you to run a check - the components of this browser are often used in various programs and are a potential "security hole" that should be closed.

Cleaning the system- partially duplicates the previous category, but does not affect the places where data about user actions are stored.

I recommend checking your system in categories System problems and Browser settings and tweaks by selecting the degree of danger Moderate problems. If the viruses did not touch the settings, then most likely you will be offered only one item - “autorun from removable media is allowed” (flash drives). If you check the box and thus prohibit autorun programs from flash drives, then you will at least partially protect your computer from viruses distributed on flash drives. More complete protection is achieved only with and working.

Cleaning the system from unnecessary files

Programs AVZ can clean the computer from unnecessary files. If the hard disk cleanup program is not installed on the computer, then AVZ will do, since there are many possibilities:

More about points:

Clear system cache Prefetch- cleaning the folder with information about which files to load in advance for quick launch of programs. The option is useless, because Windows itself quite successfully monitors the Prefetch folder and cleans it up when required.
Delete Windows log files- you can clean up a variety of databases and files that store various records of events occurring in the operating system. The option is useful if you need to free up a dozen or two megabytes of hard disk space. That is, the benefit from using is scanty, the option is useless.
Delete memory dump files- when critical errors occur, Windows stops its work and shows a BSOD (blue screen of death), at the same time saving information about running programs and drivers to a file for later analysis by special programs to identify the culprit of the failure. The option is almost useless, as it allows you to win only ten megabytes of free space. Clearing the memory dump files does not harm the system.
Clear Recent Documents List- oddly enough, the option clears the Recent Documents list. This list is in the Start menu. You can also clear the list manually by right-clicking on this item in the Start menu and selecting "Clear Recent Items List". Useful option: I noticed that clearing the list of recent documents allows the Start menu to display its menus a little faster. The system will not be damaged.
Clearing the TEMP Folder- The holy grail for those who are looking for the cause of the disappearance of free space on the C: drive. The fact is that in the TEMP folder, many programs store files for temporary use, forgetting to “clean up after themselves” later. A typical example is archivers. Unpack the files there and forget to delete. Clearing the TEMP folder does not harm the system, it can free up a lot of space (in especially neglected cases, the gain in free space reaches fifty gigabytes!).
Adobe Flash Player - cleaning up temporary files- "flash player" can save files for temporary use. They can be removed. Sometimes (rarely) the option helps in combating Flash Player glitches. For example, with video and audio playback problems on the Vkontakte website. There is no harm in using.
Clearing the cache of the terminal client- as far as I know, this option clears the temporary files of the Windows component called "Remote Desktop Connection" (remote access to computers via RDP protocol). Option seems to be does no harm, it frees up space from a dozen megabytes at best. There is no point in using it.
IIS - Delete HTTP Error Log- long to explain what it is. Let me just say that it is better not to enable the option to clear the IIS log. In any case, it does no harm, no benefit either.
Macromedia Flash Player- item duplicates "Adobe Flash Player - Cleaning Temporary Files", but affects rather ancient versions of the Flash Player.
Java - cache clearing- gives a gain of a couple of megabytes on the hard drive. I do not use Java programs, so I did not check the consequences of enabling the option. I don't recommend turning it on.
Emptying the trash- the purpose of this item is absolutely clear from its title.
Delete system update installation logs- Windows keeps a log of installed updates. Enabling this option clears the log. The option is useless because there is no free space to win.
Remove Windows Update protocol- similar to the previous paragraph, but other files are deleted. It's also a useless option.
Clear the MountPoints database- if icons with them are not created in the Computer window when connecting a flash drive or hard drive, this option can help. I advise you to turn it on only if you have problems connecting flash drives and disks.
Internet Explorer - clear cache- clears temporary files of Internet Explorer. The option is safe and useful.
Microsoft Office - clear cache- cleans temporary files of Microsoft Office programs - Word, Excel, PowerPoint and others. I can't check the security options because I don't have Microsoft Office.
Clearing the Cache of the CD Burning System- a useful option that allows you to delete files that you have prepared for burning to discs.
Cleaning up the TEMP system folder- unlike the user's TEMP folder (see point 5), clearing this folder is not always safe, and it usually frees up a little space. I don't recommend turning it on.
MSI - cleaning the Config.Msi folder- this folder contains various files created by program installers. The folder is large if the installers didn't complete their work correctly, so clearing the Config.Msi folder is justified. However, be warned - there may be problems uninstalling programs that use .msi installers (for example, Microsoft Office).
Clear task scheduler logs- The Windows Task Scheduler keeps a log where it records information about completed tasks. I do not recommend enabling this item, because there is no benefit, but it will add problems - the Windows Task Scheduler is a rather buggy component.
Delete Windows setup protocols- winning a place is insignificant, it makes no sense to delete.
Windows - clear icon cache- useful if you have problems with shortcuts. For example, when the Desktop appears, the icons do not appear immediately. Enabling this option will not affect system stability.
Google Chrome - clear cache is a very useful option. Google Chrome stores copies of pages in a folder designated for this purpose in order to open sites faster (pages are loaded from the hard drive instead of downloading via the Internet). Sometimes the size of this folder reaches half a gigabyte. Cleaning is useful in terms of freeing up hard drive space; neither Windows nor Google Chrome affects stability.
Mozilla Firefox - Cleaning up the CrashReports folder- every time a problem occurs with the Firefox browser and it crashes, report files are generated. This option deletes the report files. The gain of free space reaches a couple of dozen megabytes, that is, there is little sense from the option, but there is. The stability of Windows and Mozilla Firefox is not affected.

Depending on the installed programs, the number of points will be different. For example, if the Opera browser is installed, you can clear its cache too.

Cleaning the list of startup programs

A sure way to speed up the computer's startup and speed is to clean the autorun list. If unnecessary programs do not start, then the computer will not only turn on faster, but also work faster too - due to the freed up resources that will not be taken away by programs running in the background.

AVZ is able to view almost all loopholes in Windows through which programs are launched. You can view the autorun list in the Tools - Autorun Manager menu:

An ordinary user has absolutely no use for such powerful functionality, so I urge don't turn everything off. It is enough to look at only two points - Autorun folders and run*.

AVZ displays autostart not only for your user, but also for all other profiles:

In chapter run* it is better not to disable programs located in the section HKEY_USERS- this may disrupt other user profiles and the operating system itself. In chapter Autorun folders you can turn off everything you don't need.

Lines marked in green are recognized by the antivirus as known. This includes both Windows system programs and digitally signed third-party programs.

All other programs are marked in black. This does not mean that such programs are viruses or anything similar, just that not all programs are digitally signed.

Don't forget to stretch the first column wider so you can see the name of the program. The usual unchecking will temporarily disable the autorun of the program (you can then tick it again), selecting the item and pressing the button with a black cross will delete the entry forever (or until the program writes itself to autorun again).

The question arises: how to determine what can be disabled and what is not? There are two solutions:

First, there is common sense: by the name of the .exe file of the program, you can make a decision. For example, Skype program when installed, it creates an entry to automatically start when the computer is turned on. If you do not need it, uncheck the box ending with skype.exe. By the way, many programs (including Skype) can remove themselves from startup, just uncheck the corresponding item in the settings of the program itself.

Secondly, you can search the Internet for information about the program. Based on the information received, it remains to decide whether to remove it from autorun or not. AVZ makes it easy to find information about points: just right-click on the item and select your favorite search engine:

By disabling unnecessary programs, you will noticeably speed up the startup of your computer. However, it is undesirable to disable everything in a row - this is fraught with the fact that you will lose the layout indicator, disable the antivirus, etc.

Disable only those programs that you know for sure - you don't need them in autorun.

Outcome

In principle, what I wrote about in the article is akin to hammering nails with a microscope - the AVZ program is suitable for optimizing Windows, but in general it is a complex and powerful tool suitable for performing a variety of tasks. However, in order to use AVZ to its fullest, you need to thoroughly know Windows, so you can start small - namely, with what I described above.

If you have any questions or comments - under the articles there is a comment block where you can write to me. I follow the comments and will try to answer you as soon as possible.
