Yet another ccsvchst.exe CPU hog post

I have searched the forums and tried most of the solutions for this, but ccsvchst.exe still turns up every ten minutes or so and hogs 100% of one of my CPUs. This drives the temperature up, and sets the fan off at full steam, and I simply don't want to listen to the noise. 

 

This is so annoying that I am considering uninstalling 360 completely and just running without. So any help will be received with open arms.

 

My system on a Sony Vaio SE:

 

Win7 Pro 64 bit

2.8GHz Intel Core i7 CPU

8Gb ram

256Gb SSD HD

 

Norton:

360 Premier Edition

Version: 5.2.0.13

 

As you can see from the screenshot, ccsvchst.exe runs for about ten minutes every ten minutes. Driving me nuts, so any solutions welcome.
