I hate to say it, Jp, but Raptor might be right. You have so many infections and there's no telling how many of them are self-replicating or might be letting other infections in. You can do scans with AVG, TrojanHunter, and SUPERAntiSpyware (not at the same time, of course), but I don't know how much they'll be able to help you. If you can somehow manage to get the number of infections down to...maybe 20, it wouldn't be quite so overwhelming. But I really don't know if you can manage that. Many infections require special needs and techniques...reformatting might not be the most convenient/desired route, but it's definitely easier.
