Crippling High Disk Usage

I'm getting a really high disk usage from the ccsvchst.exe file as soon as my computer turns on and it continues until I put Norton Internet security on silent mode. When it isn't on silent mode and disk usage is high my computer struggles so much clicking on files moving between windows and things like that, this issue is seriously crippling. I've looked at a couple of other threads and have yet to see someone actually solve this issue and unless someone does I'm going to suggest just uninstalling Norton and moving on to a better product.
