Malwarebytes Anti-Malware Free (Mbam) version 2.0 is an on-demand scanner that, in addition to your real-time Anti-Virus (AV) software, protects your system against malware.
Malwarebytes is not an Anti-Virus (AV) program, it addresses other types of malware often overlooked by AV programs. No single application can identify and eradicate all types of malware.
Your first line of defense against infection is a real time AV program with an up-to-date engine and virus definitions actively protecting your system with periodic scans scheduled.
Your second line of defense against malware are on-demand scanners. If it is suspected that malware is on your system, an n-demand scanners can check for and clean any malware it detects.
It is good practice to run Mbam once a week.
