Really, it was on a CD I tried to install a game from. A trojan, no less. It's not doing any harm that I am aware of, but it's still annoying as hell, especially as Norton virus warnings pop up indefinitely. The virus gets detected a lot alright, but Norton Antivirus is unable to remove it, much less quarantine it. I tried to remove it in failsafe mode, but well... Failed. It's still there, and those "OMG oh noes you have a virus" warnings are really annoying. Anything I can try before reformatting my PC?
