Recently, my computer was infected by the auto virus, which came from a mobile hard drive. This virus is really stubborn because many solutions I found were not able to solve the problem. The key issue is that the virus file would be recognized as part of the antivirus software itself by the antivirus software. Yesterday, I suddenly saw this article on Westward Info. I tried it on two infected computers at my home... Now, the computers have returned to normal. Now, I'd like to recommend this article to everyone.
