ccSvcHst Processor Usages High with WOW World of warcraft?

Ok, here is the problem.  I start up the computer up and ccSvchHst starts checking the files.  When it gets to World of warcraft, It starts the wow launcher, then starts checking the entire art.mpq, etc file like crazy.  It kills like 99% of my cpu and 100% of my hard drive transfer for at least 15 minutes.  It does anywhere between 400-800 meg and sometimes 1 gb of pure reads and I can't stop it.  I finally tracked it down to ccSvchst process.  I need to stop it from checking wow files every time it starts up.  Please help!!!.

 

Thx.
