TRSDKd error

I have Windows XP Pro.  I recently updated to Norton Internet Security 2009.  When I go to shut down my computer now I always get this error:

 

TRSDKd ww: c\Program Files\Norton Internet Security\Norton Internet Security\engine\

 

I have to choose to end the program in order to shut down.  I have done a complete system scan.  Any idea what this is or how I can resolve the error?

 

Thanks.
