I set the application monitor to untrusted, which is the same as blocked in comodo, so unknown applications are then blocked from running. I also go into settings, threats and exclusions and check the box next to 'other' I've set the file antivirus to scan all files and set the heuristics to deep scan, but the 2 settings that I believe really matter are: setting the application monitor to untrusted and checking the 'other' box under threats and exclusions.
