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

I don’t think so, KAKA\_112 .

• The problem is not with a "Full Scan Feature" that’s been scheduled by the user.
• Unchecking the AC power condition doesn’t “unschedule” anything.
• Adding a weekly trigger doesn’t “reschedule” anything. It would only add another Quick Scan that runs weekly, in addition to the Quick Scan that’s already being triggered every day by Automatic Maintenance. The Windows Defender Scheduled Scan task is a Windows System task that’s managed by Windows Automatic Maintenance. You shouldn’t be touching it.
• Hopefully, “rescheduling” the other three Windows Defender maintenance tasks to run on a weekly basis (worst idea yet) would just add another instance of the task – because if it actually put these tasks on a weekly schedule it would seriously impede the maintenance workflow. These tasks were designed to run daily.
• And the embedded “PRO TIP” for running Reimage Plus… well that should tell you everything you need to know about the author’s credibility.

It’s unfortunate that the Microsoft Community doesn’t provide us with any  kind of “recovery options” for dealing with threads like this, that get off to a bad start, and then go downhill from there. But I guess we should really blame Microsoft for all the confusion, since they failed to provide users with any kind of documentation at all for Automatic Maintenance, and also neglected to lock down the Automatic Maintenance tasks in order to prevent them from being turned into a workshop for stupid hacks.

In case anyone is interested, here’s the correct way to reschedule the Windows Defender Scheduled Scan task (the Automatic Maintenance scan):

But truth be told, the Automatic Maintenance scan doesn't really make for a very good “scheduled scan”, because it won’t run “on schedule” if you’re using your PC at the scheduled time. If you keep busy on the PC, Automatic Maintenance will just sit back and wait for you to stop before starting the scan, in order to keep the maintenance tasks from interfering with your work. So if you're looking for the old-fashioned kind of scheduled scan, that actually gets going at the scheduled time, and runs without interruption – then you’ll need to set up your own scheduled task:

I recently resolved this issue by modifying the "schedule" of Windows Defender. Anyone, willing to try that can attempt the steps listed at antimalware service executable

Jeffrey,

Thanks for your help with this.

I had Microsoft support remote into my computer and they changed my virtual memory to 3456KB.

I have not had this problem since.

I think that fixed it for me.

Thanks,

Tony

I am having this issue on a Windows 10 Home 64Bit Dell laptop computer.

I did not read all of the posts in this extensive thread, but from reading a lot of it, I get the impression that there is no answer to fix this problem.

Please tell me that I am wrong and tell me where to find the answer.

Thanks,

Tony
