Infected PC #2: I have a downloaded Malwarebytes program that was showing in the tray, but has been disabled so that it won't open. When I tried to open the scan function, nothing happened. I tried to start Windows XP in the safe mode (all options: with networking, without networking,with DOS prompt) but it just results in a continuous loop that never loads Windows, but just takes me back to the motherboard screen.I don't have to hit F8.... It just keeps going on it's own, back to the boot mode selection screen and back to the motherboard screen. Ugh. Help please.
