Re: cpu working 100%

Hi,

 

Have you installed third party security software? What version of Windows are you using?

 

You may have more than one Anti-Virus (A-V) resident scanner running. If you are using other A-V software you should turn off Windows Defender.

Re: cpu working 100%

Hi,

 

Third party software would be another A-V program such as Norton, or Eset, Trend Micro, or Kaspersky.

 

Windows Defender processes in Task Manager are as follows:

 

MSASCui.exe

 

MsMpEng.exe

 

Disconnect from the Internet, Open Control Panel - Windows Defender- and temporarily turn off Windows Defender.

 

Check CPU usage. Has CPU usage normalized? At idle your CPU utilization should be one to two percent.

 

Reboot your PC then turn on Windows Defender. Check if CPU usage at idle maintains a one to two percent utilization level.

 

If your CPU is still in overdrive you may consider replacing Windows Defender with one of the free A-V programs available for home use.

 

AVG

 

Avast
