Can one prevent Antimalware Executable to start hogging CPU for extended periods each time some network adapter gets active?

I followed the instruction till I got to the windows defender under the library path:

however in my case non of the option checkboxes are selectable i.e. they are greyed out. So it seems in the case of my windows 10 machine, I cannot do so.

I had exactly the same problem and I followed the

steps you gave, but my computer won't let me uncheck

the boxes, what should I do?

I have the same problem!!! I have read every post on this thread 10 times or more.

I can't stop it from pulling 70% cpu, and causing everything to be slow like windows 98!!

Between this and search filter host, I have about had it with windows all together.

I am in another thread and can't get java to work on windows 7, so no weather radar for me!!!

I will NEVER spend 1 more penny on anything Microsoft!!!

I have owned every operating system since windows 95.

I am beginning to think the only cure is to take both of these to the Pawn Shop.

Windows XP was the only operating system that Microsoft has ever released that worked!!

I was ripped off by Windows ME and Vista. I haven't had a job in 3 years due to heart trouble.

I hope Bill Gates Enjoys my money for **** that don't work. He should give me some money!!!

Maybe he just likes torchering Disabled American Veterans like me!!!!!!!!!!!!!!!!

I was in my doctors office today waiting and 4 other people were complaining about

windows 8 8.1. ! guy said he just bought a MAC after years of aggravation. He said it was

the best move he has ever made. It's Not just me!!! I ask why does Bill Gates do this, Release

****. I can't buy a new computer on my budget right now, I can hardly afford food!!!

And Bill gates is giving away money, MY MONEY!!!!! I am so mad right now, I am seeing stars!!

GOOD Night,

Tim Robins.

P.S. I gave away my gun to prevent me from committing suicide due to this ****!!!!!

I have Had IT!!! 2 computers less than 2 years old, and neither 1 Works Right!!!

And of course Microsoft stopped supporting XP, BECAUSE IT WORKED!!!!!

The lower pane of the main Task Scheduler window is inactive. In order to edit the conditions for any task you need to right-click on the task and select “Properties”, or double-click on the task. However, unchecking the items in the conditions tab won’t prevent the Windows Defender Scheduled Scan from running, as I’ve already mentioned. Automatic Maintenance runs the Windows Defender Scheduled Scan task daily, and there are quite a few reports of it failing to yield to user activity, as it should do in its default mode. Here are a few things you can try if the Windows Defender scan doesn't stop whenever you start using your computer:

1.) Uninstall any other potentially conflicting (real-time) AV products. The most common cause of excessive CPU utilization and scan times is a conflicting AV product, although this same excessive-workload issue can also be caused by third-party monitoring or logging utilities.

2.) Reschedule Automatic Maintenance (in the Action Center) for a time when the PC will be on but not in use.

3. While it’s generally not a good Idea to modify the Windows Defender Scheduled Scan task, there’s a report here (by Rob Sherratt) that enabling the idle condition might be a workaround for this issue:

4.) Disable the Windows Defender Scheduled Scan task by right-clicking on the task and selecting “Disable”.

5.) Install a third-party AV product; which should disable Windows Defender.
