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?

    If you want to (if you can), you should be able to get your hands on a Win7 DVD and overwrite the current Win8 installation fully. You most likely already know you can do this, but still... I consider it a must to separate user data and app data (different partitions) because it's the easiest way to be assured of the safety of your data without backing up or using other drives. Just saying, I keep a Win8.1 installation and a Data partition, then the third is system-reserved and the fourth keeps switching between Ubuntu, Win7 and Win10. Easiest for me. When everyone that uses this computer listens to me and stores personal data on Data, there's nothing short of drive failure or a format that could cause them to lose their data.

    This website won't let me reply to the thread, only to a specific post. Windows is the closest thing to a virus that I have on my computer. They will probably delete this post. You cannot stop the OS from hogging memory. Good game bro. Nice try.
