SONAR in v16.5.0.135 - Changed?

In the past, N360 v2.x and NIS2009 (starting with v16.0.0.125) have had different SONAR detection results.  N360 always ignores a component in my programming suite that assists in compiling C code for TI processors; NIS2009 has always flagged this file’s process and SONAR has deleted / quarantined the file.  Now when I run my programming suite, NIS2009 v16.5.0.135 does not pick up / flag the component.

 

Two questions:

1)      Does the Custom Un-install (which saves Antispam, Identity information, etc.) save the SONAR exceptions also?

 

2)      If this is not true, then was the detection capabilities of the NIS2009’s SONAR changed or altered?
