Automatic Antivirus Protection Unexpectedly Turned OFF

I have the dreaded yellow triangle telling me that "The Auto File Scan feature is temporarily not working.  Try running live update?.  When I try and configure the auto-protect to "scan everywhere" it lets me choose "on" and when I hit OK I get two error messages:  1) Norton AntiVirus Error Auto Protect could not load the scan engine.  Please run liveupdate to get the latest version and  2) could not load real-time scanning.  Make sure that it is properly installed.  

 

I have run live update and it does not fix the problem.  

 

FYI, I recently had to uninstall and reinstall Norton.  

 

Appreciate any help to get this problem fixed.

 

Thank you,

Dawson
