I have a virus that eats up all of my available disk space. I have deleted most of my programs, and after the deletions are done, the space I made available fills right back up again. I ran (online) Norton/Symantec, trend micro house call, and AVG. I had to do it online since I need more disk space to run a resident virus program. The only way I can stop the monster from filling up any space made avalable is to delete a program and come up in safe mode. As soon as I reboot to full windows , the space I made availabe fills up. It seems to leave at least 170 to 200 Meg available. The PC is a Dell laptop with a 10 gig drive. And at this point, few programs!
