Hey guys, I've got a strange problem. My computer about 4 days ago just suddenly began running incredibly slow. It boots up slow as all get out, loading the programs from system tray is incredibly slow. When I open programs(internet explorer, for example) it takes literally about 10-12 seconds to even begin opening, then it freezes constantly. This applies to every program I open. Just all around very slow operating. I've ran the HouseCall Free Online Virus Scanner and it found some WORM virii, but I cleaned and deleted those files. I thought that might be the problem, but the problem persists even after successful clean virus scans. I defragged the drive and that didnt help. I also used disk clean and that hasn't helped either. Advise appreciated! Thanks in advice guys.
