To date, the livestock of viruses is calculated by hundreds of thousands! Among such a variety, catch this infection to your computer easier!

In this article, we will consistently consider how you can remove viruses from a computer in various situations.

1. What is a virus. Symptoms of infection of viruses

The virus is the prolonged program itself. But if they only multiply, it would not be so zealo to fight them. Some of the viruses can exist at all at all without interfering with the user until a certain point and at the hour of X will give himself aware of: can block access to specific sites, delete information, etc. In general, interfere with the user to work normally for PC.

The computer when infected with the virus begins to behave unstable. In general, symptoms may be dozens. Sometimes the user does not even recognize that he has a virus on PC. It is worth alert and check the computer by antivirus if there are the following signs:

1) Reducing the speed of the PC. By the way, about that, (if, of course, you have no viruses) we understood earlier.

2) Files cease to open, part of the files can be corrupted. Especially, this concerns programs, because Viruses infect EXE and COM files.

3) Reducing the speed of programs, services, faults and application errors.

4) Lock access to part of the Internet page. Particularly popular: VKontakte, classmates, etc.

5) Locking Windows OS, please send an SMS to unlock.

6) Loss of passwords from access to various resources (by the way, usually the Trojan programs are engaged in this, which, however, can also be attributed to viruses).

The list is not complete, but if there is at least one of the items - the probability of infection is very high.

2. How to remove viruses from a computer (depending on the type)

2.1. "Normal" virus

Under the word, usual should be understood that the virus will not block you access to work in Windows.

To begin with, you should download one of the utilities for checking the computer. Some of the best are:

3) open the avz.exe file.

4) After starting AVZ, you will have three main tabs: search area, file types and search options. In the first tab, select Disks to be checked (be sure to select system Disk). Put the checkboxes for the program to check the running processes, conducted heuristic check of the system and was looking for potential vulnerabilities. In the method of treatment, enable the options that will determine what to do with viruses: delete, or ask the user. Screenshot with listed settings is slightly lower.

5) In the Types of File Types, select Verify all files, enable check all archives without exception. Screenshot below.

6) In the search parameters, mark the maximum heuristics mode, turn on the detection of Anti-Rootkit, search for keyboard interceptors, correction system errors, Search for Trojan programs.

7) After setting the settings, you can click on the Start button. Check lasts for quite a long time, at this time it is better not to perform other processes in parallel, because AVZ part of files blocks. After checking and removing viruses - restart the PC. Then install some and check the computer fully.

2.2. Virus blocking Windows

The main problem with such viruses is the impossibility of working in the OS. Those. In order to cure a computer - you need either the second PC, or pre-prepared discs. In the extreme case, you can ask for friends, friends, etc.

By the way, there was a separate article, be sure to look!

1) To start, try with the command line support (this boot point will appear if you press the F8 button when the PC is loaded, it is better, by the way, press several times). If you managed to boot, enter "Explorer" to the command prompt and press ENTER.

In this system utility you can see that you have in autoload. Turn off everything!

2) If the computer fails to load in safe mode, you will have to resort to Live CD. This is special boot diskWith which you can check the disk for viruses (+ delete them, if any), copy data from HDD to other media. To date, three specialized emergency disks are the most popular:

Dr.Web® LiveCD - emergency drive from Dr. Web. Very popular set, works trouble-free.

LiveCD ESET NOD32 - Probably, the utilities on this disk are carefully checked by your hDD. Otherwise, explain long check Computer does not work ...

Kaspersky Rescue Disk 10 - disk from Kaspersky. Convenient, quickly, with the support of the Russian language.

After you download one of the three disks, or on the USB flash drive. Then turn on the download queue in the BIOS queue boot records Drive or USB (). If everything is done correctly, Live CD will boot and you can proceed to check hard disk. Such a check is usually (if viruses are found) helps to get rid of the most common viruses that remove other paths is unlikely to succeed. That is why, at the beginning of this chapter, a footnote was made that the second PC should be needed for treatment (for it is impossible to write down the disk). It is very desirable to have such a disk in my collection!

After treatment using Live CD, restart the computer and install a full-fledged antivirus program, update the databases and turn on the thorough computer check mode.
