Malwarebytes Anti-Malware Free utilizes Malwarebytes powerful technology to detect and remove all traces of malware including worms, trojans, rootkits, rogues, dialers, spyware and more.

Malwarebytes Anti-Malware Free sweeps away malware infections but does not include Realtime Proactive Protection.

Think of it like a malware-destroying broom - you can use it to clean your computer, but your computer won't clean itself (just like Mom used to say).
