FASTIO check_if_possible killing my performance

Hi-

So about once a day, my hard drive just goes ballistic along with about 20 - 30% usage on both CPU's. I run the "Filemon.exe" diagnositc tool from Microsoft and get these entries non-stop:

ccSvcHst.exe:1224 FASTIO_CHECK_IF_POSSIBLE
ccSvcHst.exe:1224 FASTIO_READ

Anybody know what this is? I suspect it's a Norton AV issue because the path listed is
Docs and Sets\User\App Data\Norton\{wierdstuff...}
but I haven't found anything conclusive to associate it with a Norton task or known issue. Of course all virus/malware scans come up clean at the moment.

Thx

 

As far as I can tell this FASTIO entry is nothing to worry about.

What I would suggest is to quickly look in Task Manager when you hear your hard drive working hard and look to see what process is using a lot of resources.

 

ccSvcHst.exe is the only thing that is using CPU cycles during this process.

 

Are you running Norton & McAfee?

 

Just Norton AV 2011 v 18.1.0.37

 

The only thing I can suggest is to completely uninstall Norton with this removal tool.

And then do a fresh install of the latest version or go for Microsoft Security Essentials which is just as good, it's free and it won't hog system resources.
