Looks like I have some really nasty virus. (Won't let me run programs...says: insufficent system resources). I can't perform the 8-step removal b/c Internet doesn't work (can't turn on firewall which was turned off by the virus, or download CCleaner). On top of that, I want to back up some files in case I have to reformat as a last resort but when I go to safe mode, the administator log in pops up and asks for a password. XP was factory-installed and I don't have a password. Tried clicking ok but keeps asking for password. Tried Ctrl-Alt-Dlt which brought me to a login with Adminstrator and a password already entered but when I clicked OK, didn't work. Tried entering my own username (which I never set up with a password) but still asks for a password. I have access to safe mode through another user's login id but no access to my own files that I want to back up. All I was able to do at this point was a disk clean up of my C drive and run avira (which I had) that detected some warnings (C: The file could not be opened; could not find any compatible Direct 3D devices) but no viruses. Do I have any other options at this point? I have a laptop with wireless access through a router so my Internet works but not on my desktop. Sigh. I've been at it for a few days and I'm wearing thin. Help someone?
