Hi there... I'm using the free version of BitDefender 2009. It found the virus I listed above, but was unable to take any action.
I apologize that I'm not very technologically inclined, so my understanding and ability to explain my situation is pretty limited. Fortunately, I got a screencapture of my findings.

I tried to take a look at the Temporary Internet Files folder where the file is apparently located, though it turned out to be completely empty. 8< The protective software I have on my computer right now are Avira, Snoopfree Privacy Shield, MalwareBites and Ad-Aware (the last two which I don't use as often).
Can anyone help me get rid of the beast the other programs didn't pick up on? Thanks so much.
