I have recently joined the community in order to help solve this problem with afore mentioned problems in the subject line.
I typed (googled) ccSvcHst and came up with a lot of sites to visit, but when I saw Norton. I immediately clicked on it. I was transfered to a post about possible solution for said problems. After reading over the persons post, and the following answers or reply's to post, it beame apparent to me that I was experiencing the same as said post. I copied and pasted it to my note pad and printed it out. One problem led to another. I was going to reply to said post but did not get the users name or anyone else that replied to it. The only info that I was able to save was the time/date stamp. I was able to find the forum that had listed said post, but came to the conclusion that it would take for ever and a day to get there, because it was dated 8-15-10.
The person who posted this said that after months of trying to figure out why his computer would hang or slow down due to Norton's Antivirus files, ccSvcHst and/or NPROTECT.EXE. that he came up with the solution. Going to his Task Manager Performance, he saw that CPU usage wouild run 100%. He said that after he read and tried many ideas from the forums and that he was finally able to "cure" what was happening to his computer. Starting with disabling Norton's Antivirus in the lower tray Notification area. He stated that you can disable it for different periods of time, and that if you did it permantely, the next restart it would show that firewall is now disabled. I don't understand that part, but anyway. So he disabled the antivirus until the next restart. After he rebooted his task manager showed normal usage.
Okay so here goes. I am experiencing a screen shut off for about 2-3 seconds, and am wondering if this might be the reason why. Is there no getting rid of this ccSvcHst.exe, or is it really a necessity while running Norton?
