I was recently infected with spyware (yes I did something stupid) and
after removing it with MS AntiSpyware software none of my CD/DVD drives
or tape drive worked. Below is the list of infections (copied out of
the antispyware software):

Krepper Trojan Downloader (removed)
CoolWebSearch.SearchX Spyware (removed)
Trojan.Delf.EF Trojan (removed)
PWS-Banker Password Stealer (removed)
BackDoor.Galapop.A Backdoor (removed)
CoolWebSearch Browser Modifier (removed)
TargetSaver Trojan Downloader (removed)
Trojan.PayTime Trojan (removed)
SpySheriff Potentially Unwanted Software (removed)
Startup.NameShifter.JV Trojan (removed)

I was able to restore my CD/DVD drives using this article:
http://support.microsoft.com/default...BLN%5D;q314060

This did not help the tape drive problem though (it is a DLT4000 hooked
up via SCSI). I'm getting an exclamation point and this error message
in device manager:

"Windows successfully loaded the device driver for this hardware but
cannot find the hardware device. (Code 41)"

Any suggestions besides doing an OS reinstall?

thanks
Ryan
