The problem is there isn’t an easy way to test it as you only get a notification that something has been scanned if there is an actual detection, if clean nothing is displayed. avast’s ashQuick.exe generally doesn’t need any switch, but some download managers insist on it.
You could download some of the eicar test files (not using that way if you get an alert you know you have the right switch, http://eicar.org/anti_virus_test_file.htm.
Have you looked at its help file of the Orbit web site ?
