How to delete the exclusions from Microsoft defender Win10?

I have problem deleting the following folders from the exclusions because my CPU is on 90% Usage because of these exclusions and I don't know when and why even they are on my list. I have updated windows yesterday and my CPU starts heating up... I scanned the PC and no threat detected. But suddenly I opened the exclusion list and found some garbage is in the list which is not able to delete while the Remove button is disabled. Is this a ransomware update attack or a malware attack on Microsoft server side which is providing vulnerable updates? Image
