I don't know if what ccsvchst.exe is useful or not, but I found that when I close icloud and dropbox, programs that are typically constantly trying to synchronize over the network, then the cpu usage of ccsvchst.exe goes down from about 80% to about 20%.

Norton has been off my laptop for two years now, yet this and three other Norton files are still active. Neither my Antivirus "Windows Defender" or my anti Malware program find anything wrong with these Norton files. They do take a small amount of memory, but I am suspicious because Norton should not be running at all on here. I don't think it is essential, but will have to do more research before deleting the files in the Norton Management folder.
It eats up large amounts of CPU capacity, sometimes 100%
My Dell Computer will not shut down normally with ccSvcHst running. ccSvcHst must be forced to close or the computer will stay on. I uninstalled Norton 360 leaving Identity Safe only installed. But if this little hunk of malware is the cause of my CPU overload trouble then OUT it goes too. I really expected much better from Norton than THIS.
The ccsvchst.exe file is automatically added to your computer upon installing the Symantec Endpoint Protection Manager

ccsvchst is serious killer you can't even access anything it keeps you continuous restarting and all your programs will be unusable due to unexpected running applications and highly used performance of CPU s0 ccsvchst is more then virus
Even if all Norton Antivirus features and updates are turned off, ccsvhst.exe seems to be using cpu whenever e-mail is checked or a program is opened.
Even if you kill the process, it restarts. Constantlt eating up memory and CPU usage.

Best practices for resolving ccSvcHst issues

A clean and tidy computer is the key requirement for avoiding problems with ccSvcHst. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the ccSvcHst.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
