Thank you for the article. My computer was several times infected with a virus, but I managed to delete them by any Antivirus. Last time my computer was infected with a troyan (Win 32, one of its modification). I formatted the C disk and reinstalled Windows OS, but the troyan was on the disk D too. So I formatted it too. In the end, I lost all of my programs, my 3198 mp3 music and videous.
