Sorry to hear of your problems, Dario. MalwareBytes is the usual tool for removing this stuff (called MBAM for short). Sometimes a virus is clever enough to keep it from being downloaded/installed/updated. Personally, I think MBAM is one program that is worth paying for to turn on the Real Time Protection (rather than running it periodically to catch things after the fact).
Britec has a lot of videos on Malware removal and a forum here: http://www.briteccomputers.co.uk/forum/virustrojanspywaremalware/ which includes info on MalwareBytes. I'd also highly recommend you install the (free) Microsoft Security Essentials (XP or 7). I'd also consider switching Anti-Virus from AVG (since it didn't prevent you from getting the trojan in the first place). I use another free one, Avira and have no complaints. You will like Windows 7, if you upgrade. Besides looking the nicest of any non-Mac OS out there you will be able to surpass the 4GB RAM limitation of XP which is especially nice for photo/video editing.
