Ed got it in #2. Also referred to as "MBAM".
Download "rkill.com" and run it right before running mbam for the first time or anytime that you suspect malware is running on your system (run rkill.com, as soon as it stops, run MBAM, do not reboot until mbam is finished) rkill will terminate all non-recognized processes, which stops the malware from running at that moment as some of them will block MBAM.
