I got virused. Ran system restore. I then got a notice at reboot that the HKDRV driver is absent. The computer lost all network, audio, USB devices. I tried to undo the restore but can not. Device manager shows absolutely nothing of the system. I tried mscofig and diagnostic boot. Did not get the missing diver message. I got a message about needing to be the system administrator - there isn't one. The device manager is still blank while in diagnostic mode.
Toshiba does not offer the system restore CD for the computer anymore.
