I recently found that anything USB that i Plug into my computer ( any usb port) xp gives me the "found new hardware" wizard w/ the error of " there was a problem installing this device--data is invalid". it's only a 256MB flash drive with nothing on it. so i put that issue aside for a while. then i got a western digital 80Gb IDE harddrive and i connected that crap in and the 'found new hardware' error comes up. SAME ERROR! the bios know's its there; device manager shows the hard disk ( and flash drive; pics below) but will not open anything. i asked my A+ teacher about it, he said that it's most likely a virus: -i am using avast 4.7 home edition -updated all virus definitions -ran a thorough scan of my entire primary hard drive -NOTHING came up infected. i've included a screenshot of my running processes just in case someone recognizes something fishy Pics: I'm training to get my a+ so anything you think would help would be greatly appreciated.
