ccsvchst.exe duplicate object

Running Windows XP with latest service pack and Norton Internet Security 2010.  Last week started

getting a error message trying to log into one of my frequent places.  History in Norton shows

Activity - unauthorized access (duplicate object).  Status - blocked.  Actor - c:\windows\system32.services.exe

Actor PID - 672.  Target - device/harddiskvolume2\program files\Norton Internet Security\Engine\17.5.0.127\

ccsvchst.exe.  Target PID - 2760.  Action - Duplicate Object.  Reaction - unauthorized access blocked.

 

Any clue as to what's happening and how to fix this?
