Are these files necessary for Ghost to run?? CCAPP.exe, CCEVTMGR.exe CCSETMGR.exe COCIManager.exe

I have Norton Ghost 10.0 Version: 10.0.3.20387 Running XP SP3 Do I need those processes I listed in the subject line to run Norton Ghost 10 ? IF NOT, how do I remove them??? I’m not updating my software at the present time either, nor do I use NAV. The only other product Norton product I use is Partition Magic 8.0 I’m trying to clean up the processes running in the background, and would like a list of the runs for these programs that way I don’t delete something that is NEEDED. Thanks
