Hi, I'm pretty new to getting rid of viruses so please bear with me. I recently accidentally hit "Run" when a pop up came up and asked me if I wished to run a program. (I was on Megaupload.com) Almost immediately afterwards, a fake "Microsoft Security Essentials Alert" popped up saying that I was infected with "Unknown Win32/Trojan." The message also pops up whenever I try to open Firefox or IE. I still have a wireless internet connection. There are some files that are "locked." When I ran a scan with AVG in safe mode, it told me there were things that were locked and could not be tested. After running Spybot Search and Destroy, it came up with 15+ items and I "removed" them all. I ran Malwarebytes' Anti-Malware and it caught 14 items and removed only some of them. I can't access the report because the folder C;\Documents and Settings is locked. Can anyone help?
