CPU occupancy abnormal troubleshooting process

1. Check that the customer cpu has been occupied at about 80%. There is no running program on it, and the exception process is svchost.exe.

2. Svchost.exe is the core process of a system, which may be caused by the failure of downloading or installing the windows update service, which leads to repeated retries of the update service.

3. First clear all the files in the C:\ WINDOWS\ SoftwareDistribution directory and restart the machine. It is recommended to back up all the files under this file first. If it is occupied, you can stop disabling the windows update service and then try again.

4. If the empty restart is still here, then continue to check the system exception process.

5. Check the display PID in the Task Manager to view the pid of svchost.

6. Right-click svchost.exe and click Properties. In general, check to see if the location of the svchost is C:\ windows\ system32, and whether the original file name of the details is svchost. If not, pay attention.

7. Enter tasklist / svc | findstr "svchost" under cmd to view the svchost.exe displayed. If the post service is "temporarily missing", combined with the judgment in step 6, it is likely to be poisoned.

8. In general, another process will be regenerated after the end of this svchost.exe, so it is recommended to install antivirus before killing it, and prevent restart after killing it. Antivirus will be automatically intercepted and isolated.

9. Then scan the virus with 360. restart the test after the scan is completed to see if the CPU is back to normal.
