That day I was finishing work on a home computer to use some of the next day, some of the files, just the beginning of the computer properly, but I do not know how he had suddenly got stuck, I use antivirus software to clean up a bit. I did not expect direct on the crash, which under scared me, quickly restart, but will not start. This time I am worried, computer files as well as the company needs it. After I came to hold the computer repair shop, they said poisoned say antivirus software does not work, does not work well. Give me a new installation of the best antivirus for PC, since the installation of this best antivirus for PC, my computer, basically there is no card before, never encountered anything like the crash.
