NAV2012 Exclusion settings

Is there somewhere other than:

 

Settings | Computer | "Items to Exclude from Scans"

and

Settings | Computer | "Items to Exclude from Auto-Protect, SONAR and Download Intelligence Detection"

 

I should exclude a folder?  I upgraded to NAV 2012 yesterday, and this morning I'm surprised by my first overnight scan's results (on both of my identically-configured computers):

 

1.  "Threats Detected" contains items in folders already input into both of the Settings above, and

2.  In one case, the path listed doesn't exist!  In other words, It said a thread was in a non-existent Z:/a/b/ folder.  (Both Z:/a/ and Z:/b/ do exist.
