Hmm

I can see some ways of making footprint lighter, like not spiking cpu when entering folders with archives. Option of not scanning archives resident would be nice. Seems to me resident scanner can be too aggressive and just hunt everything. Check with process montior. Should think it gets enough fuel from ram sticks. I don' t care about ram usage but it is very high, not just high... From what I have seen not many have taken notice. Cpu spikes for no good reason other than some parameters needs to be changes I expect to be addressed by updates. I use a little desktop program for shortcuts, program launcher thing. Had to exclude that from MSE because it simply halted program. MSE dont just look at shortcuts, they are followed to the door

Somehow random annoyance though but definitely what I would rate as very eager scanner. Complaints could be needed to keep it so good as you think it is. Not much is static in this area. The thing about default settings of auto-removal infections in the first 2 classifications is weird by obviously by design. Let us not hope for FPs then. I would have chosen "Quarantine" as default and have an unticked "Apply recommended actions..." which means clock is ticking and you only have few minutes to research before MSE go "recommended action".
Officially it is not compatible with anything. I doubt you get any MS dude to declare even Malwarebytes welcome. BS but how it is, this is another AV company no matter what they say, so not necessarily cheering about other products. Most other companies say the same, if not officially directly in your face then through user forums and FAQs.
No need to link to "opinions" since they are more or less in agreement - which could be a worry

- and say so much of the great reputable AV companies efforts last many years... but yeah it runs just fine with Malwarebytes, all I did was exclude 3 processes mbam.exe, mbamgui.exe, mbamservice.exe
