I've had this problem for quite awhile. The computer suddenly starts rebooting over and over.
I'm running windows 7 pro x64 on an asus computer.
I had been using bitdefender free antivirus but started wondering if it was causing the problem. The problem started around the time that bitdefender brought up a pop-up saying that a new version was available. When I clicked on it it wouldn't install. I ran a virus scan of the whole c: drive and it found 1 item that it said it couldn't remove because it was password protected.
I switched to windows defender/essentials.
I also suspected the problem was related to a new optical mouse and to usb ports. The rebooting seemed to stop when I would switch the port that the usb was plugged into. I then noticed that the usb controller driver was missing from the device manager. I downloaded the usb drivers from asus and the problem seemed solved, but it's started up again.
I now have a ps/2 keyboard and ps/2 mouse plugged into a usb adapter which is plugged into a usb port. It seemed like the problem started when I switched from a ps/2 mouse (with a mouse ball) to a usb optical mouse (laser).
In any case, I've still got the password protected malware and am wondering how to remove it. Bitdefender listed it as existing in the thunderbird directory : This is the log from it:
[code=auto:0]An On Demand scan has completed.
The scan took: 01:07:31

Thanks for any help.
