Windows 10: Widows defender scan is consuming lots of resources

Windows defender's scan named as "Anti-malware service executable" simply is consuming a lot of resources and is constantly running in the background. And further, if we do a manual full scan if just peeking the CPU usage I have a i5-10th gen- upper midrange, just imagine the case of a few pc that barely reaches the minimum requirements.

:)

 

Put processes that consume a lot of resource on the top of the list in Task Mananger

A main use of Task Manager is to find which program is consuming resources. Now we need to sort by CPU/sort by Disk/sort By network to find the problem. Its better if list all the huge resource consuming programs at the top of the list what ever the resource
is so we don't need to sort in most cases.
