Malwarebytes Anti-Malware Pro. Good program, probably one of the best Antimalware there is (with Emsisoft which I use, though I use it as my Antivirus) and as a volunteer who assist on their forums, I can tell you that the people behind it are simply awesome and they can put all that "awesomeness" in their products.
I voted for:
Avast- Free Antivirus
Malwarebytes- Anti-Malware Free
...and Other - Crystal Security..
(Not Including my Sandbox, Anti-Exe, Anti-Keylogger, and HIDS software)
Main (resident): KTS2017MR0 (Default Settings, in this LapTop due to participating in MalWare Hub, but powered/custom settings in my others systems)
Second Opinion Scanners: MBAM Free, ZAM, EEK, HitMan Pro Free, AdwCleaner, Norton Power Eraser, Crystal Security.
