Shut off any security applications during testing (even if safelisted). Restart them after testing (most security applications will restart on their own after a computer restart). Some security applications may use protection schemes tickled by Scrubit’s filters that fight with Scrubit during the testing phase. Since the security application is safelisted, Scrubit will allow them to continue working. During one of the filtering stages (identified by a number on the process page) a protection mechanism can be triggered by the security application which by design fights with Scrubit. Since it is safelisted, Scrubit will not fight it or send it to cleanup. This can hang up Scrubit's testing.
