Every PC owner at least once encounters viruses. They slow down the work of programs, and sometimes disable the system. To prevent this, you must carefully scan your computer for viruses and other malicious programs. This should be done 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 your computer for viruses?
Alarms may include the following symptoms:
- application programs do not work or work incorrectly;
- the computer constantly hangs or does not turn on at all;
- it is not known where the music came from that either plays or abruptly ends;
- Advertising banners appear on the desktop blocking the operation of the main applications.
It is impossible to list everything, and it makes no sense. During the existence of the Internet, mankind has developed millions of malicious programs and their number is increasing every day.
With a geometric progression , the number of antiviruses, such as Dr.Web, Nod 32, Zaitsev antivirus, which allow you to check your computer for viruses, is increasing. Kaspersky E.V. - Our compatriot, one of the leading experts in the field of information technology, has developed the most effective product for ensuring IT security.
A company called Kaspersky Lab is developing a product that allows you to not only scan your computer for viruses, but also “treat” damaged system files.
Let's look at how to scan a computer for viruses other than Kaspersky applications. This is a very important point, because it is recommended to install anti-virus programs on absolutely all computers. The developers even took care of those who do not have the ability or desire to purchase licensed versions of anti-virus databases, which not only provide an opportunity to scan a computer, but also prevent viruses from entering the system.
First of all, it should be noted the free Cureit utility of the domestic developer Dr.Web. Its fundamental difference is that it starts at the request of the user, and not automatically, like an antivirus, which, by the way, works constantly.
Among the free programs with which you can check your computer for viruses, you need to highlight Avast, AVG and Avira.
Often there is a need to check the threat not of the entire computer, but of a specific file. For owners of antivirus this is not a problem at all, but for those who still decide to do without it, there are free online services. As a rule, they are very reliable, since files are scanned by several antiviruses at once.
The most popular are the Virustotal services and the Dr.Web online scanner.
Despite the abundance of software products that allow you to check your computer for viruses, antiviruses are considered the best. Yes, the computer runs slower, but with them you can be calm about the information stored on hard drives.
Do not forget the well-known wisdom: "Avaricious pays twice." Here, as in everything else, she is fair. It is better to buy a licensed antivirus and pay for updates of the antivirus database than to restore the system and the files stored in it.
