How to scan a computer for viruses, or Prevent a cyber-epidemic

Every PC owner at least once encounters viruses. They slow down the programs, and sometimes they disable the system. To prevent this, you should carefully check the computer for viruses and other malicious programs. Do this at least once a month, and in case of emergency it is better not to hesitate. How to understand that this moment has come and it's time to check the virus on the computer?

Alarms can be the following:

- applications do not work or work incorrectly;

- the computer constantly hangs or does not turn on at all;

- no matter where the music comes from, it plays, it breaks abruptly;

- on the desktop there are advertising banners blocking the work of the main applications.

It is impossible to enumerate everything, and there is no sense. During the existence of the Internet, mankind has developed millions of malicious programs and every day their numbers increase.

With geometric progression , the number of antiviruses, such as Dr.Web, Nod 32, Zaitsev's antivirus, that allow you to scan your computer for viruses, also increases. Kaspersky E.V. - our compatriot, one of the leading specialists in the field of information technology, has developed the most effective product for IT security.

The company under the name "Kaspersky Lab" is developing a product that allows not only to scan for viruses of a computer, but also to "treat" corrupted system files.

Let's look at how to test a computer for viruses, except for Kaspersky programs. This is a very important point, because it is recommended to install antivirus software absolutely on all computers. The developers took care even of those who do not have the opportunity or the desire to purchase licensed versions of anti-virus databases, which not only make it possible to check the computer, but also prevent the virus from entering the system.

First of all it is necessary to note the free utility Cureit of the domestic developer Dr.Web. Its main difference is that it runs at the user's request, and not automatically, as an antivirus, which, by the way, works constantly.

Also among the free programs with which you can check for viruses on your computer, you need to highlight Avast, AVG and Avira.

Often there is a need to check the threat not of the whole computer, but of a particular file. For antivirus owners, this is not at all a problem, and for those who still decide to do without it, there are free online services. As a rule, they are very reliable, as the files are tested at once several antiviruses.

The most popular services are Virustotal and Dr.Web online scanner.

Despite the abundance of software products that allow you to scan a computer for viruses, the best are considered to be antiviruses. Yes, the computer is slower, but with them you can be calm for the information stored on hard disks.

Do not forget the well-known wisdom: "Miserly pays twice." Here, as in everything else, it is fair. It is better to buy a licensed antivirus and pay for updates to the anti-virus database than to restore the system and the files stored in it.
