bit of a virus problem... or not?

hey, quick question.

i went to charlieoscardelta.com to register for the cod 4 beta. I did that, and i went back today to see if it was up. sadly enough, i wrote 2004 in the age confirm gate. After deleting cookies, i could still not get in. The other PC is slow, so i went to firefox.com to d/L firefox. As i went to click run, AVG identified it as a virus. I stopped it, and then realized it was probably a false positive. I went to do a full system check. It turned out that 32 files were infected with trojan horse generic6.UMS. i think i deleted all of em, but i did it again and there were 6 mroe. just suggestions if possible, im pretty decent with comps, but never have had a virus.

For me: if i hade a virus and the anti-virus couldn't delete it, I delete it manually by going to the virus location.

You can know the location of the virus from the anti-virus.
