Have a Dell system with a 40GB HD that was loaded (1,500 files and registry keys effected) with spyware, adware and trojans. HD is only 30% full. When I was removing these nuisances the computer froze. After hard boot I heard the HD make a screech on reboot and now it cannot find the C: drive. I assume the drive is gone. It is asking for a reboot disk in A: There are documents on it that I need to recover before attempting a reformat or partition. The OS is Win ME. Suggestions?
