Hello, sorry if my english is bad..
This problem has been make me worried or something like that since yesterday and It's won't stop until now. Whatever I do or if my system in idle state, ccsvchst.exe always take 12% - 15% of CPU Usage and never went down. And Norton folder inside ProgramData folder always modified every minute (and this one since last week). One more thing, the memory consumption goes high above 300MB and 500MB (peak).
I just want to know, what's Norton do? I'm using Norton AntiVirus 2011 last update (both engine and definition).
Here some screenshots of Windows Task Manager, Process Explorer and DiskPulse (disk activity monitoring app).
