This is the most current explanation by David H. Lipman
, a trusted Security Colleague and Malware Researcher/Analyst.
MBAM is not an anti virus application and does not replace an an anti virus application. MBAM is an adjunct, complimentary, anti malware application.
In its role as a adjunct, complimentary, anti malware application it has limitations in aspects that the anti virus application performs in its role. MBAM does not target script files...It also does not target document files...media files...MBAM targets mainly non-viral malware. The exception being a virus dropper (a malware file that drops a virus and starts a virus infection but is not infected with the virus) and worms (such as Internet worms and AutoRun worms). MBAM is incapable of removing malicious code that has been prepended, appended or cavity injected into a legitimate file. That means if a file infecting virus infects a legitimate file MBAM will be unable to remove the malicious code...MBAM is not a historical anti malware solution. That means it will not target old malware. It's intent is to target 0-Day malware. Malware that is infecting computers Today with malware found in-the-wild, Today...With all the things that that MBAM can not do, it is not an anti virus application and it remains an anti malware application which relegates it to its complimentary position.
Dave provides the same explanation in this topic at Malwarebytes
where he provides assistance on the forums board.
That indicates to me that Malwarebytes 3.0 Premium
is still better served as an adjunct anti-malware solution
to complement and strengthen your protection when utilizing a traditional anti-virus solution.
