ccsvchst.exe

I recently update my Norton product.  At first it didn't work.  I contacted Norten and had a Norton expert spend several hours over days to fix the problem which was Norton caused and finally it was stated to be fixed.  The next day I noticed when I turned on my computer it took a long time to start up Windows XP, after some searching I found that ccsvchst.exe was using up all the cpu for many minutes at start up before letting something else run on the system.  I notice that there are many many notes on this community board relating to CCSVCHST.  It seems NORTON has a problem that it should fix.  I worked on software support and instalations on main frames for 30 years and could not imagine how a company could sell a product that has so many problems.  If them do not give me a fix soon I will find another program for security support.
