Yx writes "CHRONOMIUM Virus Live is a GPL automatic decontamination LiveCD. It can without installing anything on your computer, seek and destroy viruses found on it. It is very useful when viruses have taken over a computer, and made it unable to work correctly. In its new 0.9 version, the GPL flavour is fully functional. So if you're doomed by those petty viruses, just try it, it may help you much! Download it here."
