I get a defense+ popup every time I start windows for mpsigstub.exe
I believe it is a windows app, and no matter what I choose (trusted app/windows system app, etc) it still asks me everytime. Very annoying.
I think this belongs to the ■■■■■■ program named Windows Defender. The reason our friend isn’t able to set it as trusted application, is because (I think I remember correctly) it is being executed under a different folder every time!
