I accidentally found a very strange process in the task manager, quickly swallowed up 50% of my CPU resources, and it was continuous. So I finally got a new look at Google.


A lot of Q & A products are all clear




Under normal circumstances, there should be two ccsvchst processes in the system. Path: X:/Progamme files/common files/symantec shared/ccsvchst.exe
Ccsvchst.exe is
The Framework Service Process of Symantec products.
If the CPU usage is too high, you can use the following methods to try again:
Right-click my computer> Management> services and applications> services
Turn off the Automatic Updates Service and change it to manual
Clear the "C:/Windows/softwaredistribution" Directory
Ccsvchst. EXE is a virus disguised
SVCHOST. EXE is a system process. He imitates this. You said this system does not have this process.




Correct Solution


After some in-depth exploration, it was found that the original problem was that the background process of noton anti-virus was doing its own thing and active LiveUpdate. The CPU usage was as high as 50%, I feel very discriminatory for such measures without notifying users.



  • Enable Norton Internet Security
  • Choose "Management Panel"> "computer"> "Settings"> "computer settings"> "Update"> "active LiveUpdate ".
  • Disable "active LiveUpdate" and "Pulsating Update"
  • Restart

Done !!!
