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.

7. Threat detection results are presented in the main window of the Scan menu.
If no threats were are detected, you can close the utility. This does not mean that your system is clean, it only means that Mbam did not detect any malware. Additional scans using different on-demand scanners might be advised by SF members. Each scanner has a particular focus of design and detects malware using different criteria.

If SF members are assisting you, let them know that Mbam did not find any threats

Threats detected during an Mbam scan are reported and automatically moved into quarantine. The threat(s) are isolated in the Mbam quarantine and can remain there until you are certain of the correct disposition of the file(s). Note that other malware scanners or AV applications might report the quarantined file as a threat.

I installed Malwarebytes on a client's computer last week. I notice it is now a yearly subscription. When I bought it, it was a "lifetime" subscription.

Yeah, that's the Pro or Premium version. This basically just covers the free version.

Great tutorial!

Just referenced it in a post, but I noticed the screenshots indicate that "Scan for Rootkits" is enabled but AFAIK it's off by default. A note on that would be great!

Thanks Tookeri - good catch

I intentionally left the default values undefined in this tutorial. Mbam can change them at any time and rather than chase any changes they make, I simply say run with the default settings.

Links to Mbam docs and videos are provided in step 1.

The scan log image in step 10 was replaced with one showing the default scan options (rootkits disabled)

Hitman Pro vs Malwarebytes' Anti-Malware
Which one do you guys prefer and why? I've seen some people saying that they have had nasty infections that nothing could get out (Malwarebytes, AVG, MSE, NOD32, etc.) but then when they used Hitman Pro it found the problem and got rid of it.
