My sister got the "anti-virus virus" today and I've been helping her with it by running MBAM. It seemed to do a thorough sweep, detecting 8 files on the full scan, and I immediately started a second scan just to be sure. My question is- After I got the logfile of trojans removed, it said the computer had to restart, as expected. I restarted the computer and when it was booting back up I got a message that windows could not start properly, so I selected "restore to last working point" or whatever. It started up again fine, but MBAM was gone so I had to download it again from malwarebytes. Is this reboot error common? We're running Vista (unfortunately) if that makes a difference. Thanks.
