How do I stop ccSvcHst from showing at shutdown?


I am using XP-SP3 on my laptop.I have NIS 2009 . Upon shutdown "ccSvcHst" comes up saying "not responding".

Most of the time if I click "end process" I can acheive a shutdown, but if I do nothing sometimes it will end by itself  

          and go on shuting,on others it will simply stay that way.

 

            I searched and found some threads regarding this issue in Symantec forums, but no solution, for my case.

            I always shutdown the computer , after all my programs are closed, including NIS. I guess it's on the background but

            not during a Scan.

            I suppose there is some problem, otherwise the shutdown will bw "normal" with no messages. 

          

           What causes the problem and how can I get rid of it?
