I managed to pick up a nasty Cryptic trojan horse and all my attempts to scan the drive with updated software have failed. I think this thing has got my internet connx locked up pretty well. I figured I would format my C drive after saving most of my data. Now when I give the command to format via Win Explorer or My Computer, I get the following msg: Windows cannot format this drive. Quit any disk utilities or other programs that are using this drive, and make sure that no window is displaying the contents of the drive. Then try formatting again. I tried to stop any programs using task manager, but then lost my other icons so I could not start up Win Expl or My Computer. Any help would be appreciated.
