NIS2012 - Medium Severity Entry In Security History

I am running Windows XP Home SP3 fully updated with Windows Update.

 

I have just updated my Norton Internet Security from NIS2011 to NIS2012

 

Everything seems to be working OK except that every time I logon to Windows I get the following Medium Severity entry in the Security History:-

 

Severity - Medium
Activity - Unauthorized access blocked (Duplicate Object)
Status -  Blocked
Recommended Action -  No Action Required

 

On clicking on More Details I get:-

 

Advanced Details:

Actor -  C:\WINDOWS\SYSTEM32\SERVICES.EXE
Actor PID - 808
Target - C:\Program Files\Norton Internet Security\Engine\19.1.1.3\ccSvcHst.exe
Target PID - 1324
Action - Duplicate Object
Reaction - Unauthorized access blocked

 

Actions:
No actions available for this item.

 

The Actor PID and the Target PID are different each time I logon.

 

Are these entries something that I should be worried about, and if so what corrective action should I take.
