Instruction
1. It is possible "to catch" a virus practically on any website even if it till today showed perfect purity – even the large websites regularly try to crack and infect with a virus. If it works well, the cracked website becomes a source of infection of other computers.
If the virus got into the computer, it is necessary to start at once the antivirus software in the mode of full scanning of hard and removable disks, system folders and archives. It is also necessary to turn off Internet connection and before the end of check not to use removable disks in order to avoid infection of other computers.
2. The antivirus software will report about detection of a virus by means of a sound signal or having displayed location of a virus in the log of checks. The found viruses need to be deleted by means of service of the program antivirus.
If the virus blocked the computer, it is possible to execute rather risky operation: rewrite all data, necessary and important for you, from hard drives on the removable medium and format hard drives of the computer. Removable mediums will need to be checked for presence of viruses on other computer with the qualitative antivirus software at once and to delete the infected files. Of the used programs on the formatted computer it is necessary to install the operating system and a complex again. However this option is much safer and is economic, than need to change the hard drive or completely the computer.
3. In certain cases at timely forced shutdown of the computer the process of infection with a virus can also be interrupted. However the antivirus software this action does not cancel the subsequent check.
If no independent actions help to unblock a virus and the infected computer, nothing remains how to call the specialist. Perhaps, total cleaning will help to return the computer to life though most often at so severe infection it is necessary to change a system completely.
