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

One of the most annoying habits in Windows 8 is, that the built-in "Antimalware Service Executable" (part of "Windows Defender") starts hogging my device's CPU with 60-70% (and 100% disk) for extended periods EACH AND EVERY time after I wake it up.

I wouldn't mind if it starts doing its business IN THE BACKGROUND but when I wake my device up from standby it's usually to get something done NOW and thus I find it increasingly unacceptable, that the system is always taken over by Window's defender exactly then and for up to several minutes! If I don't find a solution soon to throttle this beast, then I will disable Defender altogether!

What I noticed is, that this process seems to be actually triggered not by the system waking up, but by the network adapter becoming active. And actually, this happens each and every time ANY network adapter gets active! E.g. if my system has NO network connection at all and I plugin the network cable the Antimalware Service Executable starts. When - after it has settled again - I additionally enable Bluetooth then the Antimalware Service Executable starts its hogging business again. And if I then additionally enable the WLAN a few minutes later, it will AGAIN start to consume CPU!

So: can one decouple this? Running a scan ONCE after (re-)starting it is definitely enough, especially if Defender hasn't downloaded any new signatures since the last run! And, second, can one make Defender convince to strictly run in the background ONLY?

    I have been using Windows Since Win 95. I have tried every version.

    I learned back in 2000 it is not a good Idea to let windows upgrade

    from one version to another. I have all my stuff backed up on 16tb NAS.

    When I go from 1 version to the new one, I format the drive 3 times.

    I kill everything on that drive. Then I install the new version of Windows.

    Yes, I have to redo all my settings. But I have done it so many times, it's

    a piece of cake for me now.

    So far I like Windows 10 Pro. But I had to make a lot of changes to it.

    1. NO EDGE!!!
    2. NO Advertisements!!!
    3. I boot directly to desktop!!
    4. Start Menu X had to be there!! It's better than any start button out there!!!
    5. All Programs get installed with REVO Uninstaller!! Very Important!!!
    6. NO DEFENDER!!!

    I haven't done away with the 57 reporting processes yet. But I will Soon,

    It's Not That Hard! The Host File is my Friend!!!!

    I get the Best out of Windows. I let Windows Work for me!!!

    Hello. I first turned off defender the normal way under settings.

    I installed another Anti Virus program and defender came back and

    was running in the background. I tried 2 more times to turn off

    defender. But it still came back. Don't need 2. This turned it off for good.

    I have a program for Anti virus and Internet Security and a program

    for Malware installed. It no longer tries to use 90% of my processor

    anymore. I never said, Don't Install Protection. I never said go unprotected.

    Everyone needs An Antivirus and Malware program. But 1 that does not

    try to burn up your Processor, and nearly renders your computer almost

    useless when running. Defender used to kick in at the worst time, like

    when I would wake up my computer because I need to use it. I tried

    several times to stop defender in task manager. But get messages like

    Windows will become unstable and crash.

    This was the only way I could get Defender Out of my way!

    I have been fighting Defender since I first installed 8.1 a year ago.

    3 weeks now and defender has not come back to bother me anymore.
