Malwarebytes died with version 3 and it is not like it has got any better, quite the opposite. I give it 1-2 years before it becomes another Spybot/Superantispyware.
On my PC malwarebytes runs problem free. I'm still waiting for a nice test report. So far it seems that will take a while. @Quassar That was probably from breast cancer awareness. A pink ribon is the logo and name of a breast cancer awareness organization. I think that was why everything was pink when you took your screenshot.
