If worse comes to worse, you may have to clean your hard drive.

If you have XP or Vista, you can try a Recovery.

To clean your hard drive go to DOS Commands & FORMAT C:
First you want to put everything in My Documents, etc on a CD. Then go ahead & format. You'll have to reinstall your operating system & all software. Run a virus scan on the stuff you saved on the CD before putting it back on hard drive.
