Its all right is grasping at what it might be. But we really need some detailed information from OP on the detection before we can determine the problem/action.

@ AZKID
What scan were you running (if any) at the time of the detection/s ?

Can you give some common examples of the file names, location and malware name of the detection ?

As you said there are no other recent reports of FP detections on MBAM Pro and it is a very common companion with avast forum members. So the detailed information helps us to help you.
