Running scan from command prompt

I have Norton Internet Security version 21.3.0.12 on Windows 7 (6.1, SP1).  I run the “Full” system scan and it takes around 5 hours.  When I try to run navw32.exe from a command line it takes over 24 hours.  I am using the following command switches (/L /S+ /B+ /ST+). 

 

I assume one of these switches is requesting a more rigorous scan than a “full” scan from the interactive window.  Another possibility is that there are “whitelisted” files the interactive “full” scan keeps track of that the command line ignores. 

 

Can anyone tell me which switches I need to use to get the same “full” scan I get from the interactive window?
