There is a computer and the Internet in almost every home. And it is already difficult to imagine life without the Internet, because the World Wide Web is a colossal resource that allows you to extract information of an encyclopedic nature, use literature without visiting libraries, pay bills without leaving your home. Finally, there is a powerful entertainment reserve.
Dangerous malware, born with the Internet, are its permanent companions. A virus can cause serious harm to your computer, starting with a slight slowdown in the operation of programs and ending with a complete loss of data and paralysis of the machine.
What to do if your computer is attacked by a virus?
Option one - you do not have a security program, but you suspect that a virus has entered your computer. It is necessary to turn off the computer, after closing all windows and turning off the Internet.
The next step is to search for an antivirus program - you can buy it in a specialized store, you can ask your friends - for sure there will be at least one who has a virus protection installation program. Or at least he can download it from the Internet, install and run it.
However, the best option is to take care of the protection ahead of time. It is better to download programs of this property from trusted sources: the local network of your Internet provider, verified torrent trackers (ask in a search engine and look at the opinions on the forums). You can also buy antivirus on the Internet from an official representative of this company. It is imperative to install a localization program (if you do not speak English perfectly) - in this case, working with it will be easy and affordable.
The most popular antiviruses at the moment are: Kaspersky, Avast, Nod32, AVG. Each of them has its pros and cons, and in order to choose, you must, of course, consider each in more detail.
Option two - you have a security program and it diagnoses the virus. You have a special window in which the program asks what to do with the problem that has appeared - as a rule, these are three options: skip, treat, delete. The best option is to "cure", because during "deletion" unforeseen events may occur (if the virus has already entered the system), however, if the virus is not "cured", then it will still have to be "deleted".
If the virus has already damaged the system, it is better to contact a specialist, although you can try to restore it yourself: start - standard - service - system restore.
The most important characteristic of an antivirus is its ability to be updated, since viruses mutate, change and the protection against them must also be modified in order to be ready for an attack.
Therefore, do not forget to update the virus signature database - if it is not automatically updated - and periodically scan your computer disks for viruses.
