I fixed it by going into Program Files and finding & deleting the folder that was a random jumble of letters (sort by date modified to find the right one). That caused the Windows XP antivirus program to terminate. Once that happened, I was able to run AVG without my computer bluescreening (Windows XP 2008 Antivirus was pretty much locking up my computer whenever i tried to run Spybot or AVG). I figured out that there were a few more virussed files in ../Windows/system32 that seemed to have showed up with the fake antivirus (i think the program was just replicating the crap into system32). I deleted those foreign files, and AVG found one other virus downloader thing (in the temporary internet files... not sure if it was connected though). Everything seems to be running fine now, though. Hope you have some luck fixing your 'puter. Just look for things that have nonsensical filenames and don't seem to belong
