Window defender smart screen causing high cpu usage

When i use any app, window defender smart screen will use 100% of one of my cpu core, if i have check apps and files on under reputation-based protection. How do i stop it from using up an entire core, without reducing protection of my computer

 

High CPU usage


Done a full scan with ESET Smart Security and got nothing so that's good. After 10 mins of searching for updates I finally got an error: 0x800705b4 which is strange cause it is related to Defender and that is disabled by ESET. So now I have to deal with that I guess *Sad First time I ever had that error.
My screen is not big enough to display the long list in process tab and I also opened the 3 that had the processes inside them. Attached in this reply are 5 Processes pics for you to view. I will post another reply with the other 3. Greatly appreciate if you can see anything there that should not be there.


cheers

 

WIN10 1703 update cause Explorer.exe high CPU usage

Hi,



Glad you reached out. First, we would like to know if Explorer.exe
is the only cause of high CPU usage. Because the common cause of high CPU usage are the following:

- Windows 10 Memory leak after the update.

- Driver incompatibilities after the update.

- Multiple startup applications

We'll be waiting for your update.
