I picked up 2 computers today which had some spyware on it. Removed the spyware, but when I attempted to run defrag it cannot start. I also looked in disk management and the hard drives are not listed. The services for these are running correctly. I set chkdsk on reboot and I get the error, the type of file system is raw and it won't check. I booted from a WInXP disc I have and chkdsk worked just fine. Both computers ran chkdsk but when rebooted the same problem occurred. I've never actually seen this happen before. I attempted a repair install on one of the machines and it gets the error: Device installer error, Windows could not load the installer for Net.
