I have WinXP SP3, and ccSvcHst.exe ran all the time until the last week or so.Delayed shutdown,restart,sluggish performance in email,lots of CPU cycles. Now, it has vanished and the computer runs much better. I have Malwarebytes 2.2.1.1043,Norton Internet Security,and SpyBot active.None have told me of deleting or quarantining ccSvcHst, but it is gone & thighs are MUCH better. Allan L.
Visual Studio just-in-time -Debugger an unhandled win32 exception occurred in ccSvchst.exe{1624} khalid khan
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%. Mark Andrews
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. Tony
It eats up large amounts of CPU capacity, sometimes 100% Rick
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. Norton

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 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic 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 6resmon 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 executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.
To help you analyze the ccSvcHst.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
