My first virus. Can you guys help?

Hey everyone. A friend of mine recomended this site after he got a virus and this forum helped him out a great deal.

I was doing a virus scan this morning using AVG Free (note: I don't usually run virus scans often, every 2-3 weeks) and I found a trojan.

I'm not sure where this virus came from. I don't usually download stuff. I get my music from iTunes and my games from Steam.

I read that I was meant to submit a log so here it is. ( "I think this is it: F2 - REG:system.ini: Shell=Explorer.exe C:\WINDOWS\winlogon.exe")
