Of course who is Microsoft to define anything, right? So in the end Malwarebytes is actually an anti-virus program as the company itself defines it as a Anti-Malware so it covers that as well. Microsoft defines Malware as short for Malicious Software which includes Viruses, Worms, Spyware, Torjans etc. 'You never want two real time AVs running' I always have MBAM, SAS and a handful of other portable versions of AV, Spyware, Malware and other programs ready just to be sure as no one single AV program gets everything. It was only stated as a good second opinion because most anti-virus scanners tend to get most problems, even malware, these days but it is always good to have a second opinion. No where did anyone state Malwarebytes was an anti-virus. True, I just realized that when the moderator stated that MB and Avast free is an antivirus.People these days have got to stop mixing those up The default normal setting is set as default because its the most efficient plan for normal users. What it does is use more of your system resource inefficient being paranoid double checking everything for viruses. Also if you are worry about system impact then you shouldn't be putting your anti-virus in aggressive mode. Malwarebyte Ant-Malware is a secondary security layer design to run along with your primary anti-virus.
Malwarebytes Anti-Malware is not a primary anti-virus, when will people learn.
