I know that it is a microsoft file but when i try to scan it with MB it wont just scan it. It says it has scanned it. But the file scanned counter is still "0". When i scan another .exe file with it. It says "files scanned: 1" but not with MpStigStub.exe. So i tried to put it on Virustotal. MpStigStub.exe is hidden for VirusTotal.. Tried every way to get it on there. So i renamed it to something else. If needed it would recreate itself. After that i tried to scan it but no results.. As it wont just scan it!
