I'm going to try to explain this as best I can so please bear with me.
I updated to NIS 2011 on Tuesday and everything was working great and still is but tonight, I noticed that after a few minutes of idle time, the ccSvcHst usage goes up to about 20-25% and stays there even after the PC is no longer in an idle state. Also, the UI responds very slowly at this time as well.
As far as I can tell, no scan is being run and the HDD light is blinking constantly.
I've never experienced this sort of behavior with NIS and I wonder if anyone else is experiencing this also.
Any help would be greatly appreciated.
EDIT
NIS and my HDD has just gone back to normal activity. I'm not sure what was running as there was no mention of a scan being run.
