In fact, we're used to say that MBAM is compatible with any other antivirus, but, after all, pk is correct. It is another resident that *could* live in modern OSs side by side with other antivirus but, as we know, sooner or later we'll see both fighting for the files to scan and detect. Conflicts are on their way imho, MBAM Pro is not an exception. At least, you need to make exclusions...
