you could attempt a system restore (using a restore point, not an image) with your Win7 DVD, but that’s risky… as your restore points might be infected as well or/and the restore process may just fail… or succeed in restoring an infected system. Your best option is still to wait until Essexboy (he’s a malware expert) comes, might be tomorrow. The guy’s from England and it’s 11:15 pm there right now.
