Malwarebytes' Anti-Malware (MBAM) is an anti-malware program created by Malwarebytes Corporation. The free version of the software scans for and removes malware when run manually, and is a recommended first step if you think your computer might be infected. However, the free version does not provide real-time protection and is not a substitute for an on-demand antivirus program, but a tool to be used alongside one.

MBAM can be downloaded here.
