I downloaded that thing that Nathan posted under Classified Ads thinking it was a game, seems like it was a virus! It deleted my taskbar, I can't alt+ctrl+del, my mouse is stuck in the middle of the screen, and I can't go to my desktop. So, I'm screwed. I can't run a virus scan since I can't access the program list.
I also have DM open so I can do some DOS commands with shell(), I guess.
