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?

You said that unchek all the boxes! But i cant do it! What to do? Disk is at 100 %? What should i do? Plz help me!
THAT WAS IT! Woohoo! This, my dear Internet, is how to stop Antimalware Service Executable from slowing down your system. What a delight. Thank you, Fudge McCycle.
What's worse is this causes delays during Windows Startup that create a horrible user experience.
I fully agree! All the cool new tricks of newer Windows versions, eyecandy, new and improved UI, all of it amounts to nothing if resources keep getting eaten by these trivial processes. Even if these processes are improved to work faster, users experience the opposite if their system is not *responsive*. This is pure destruction of an otherwise good user experience. Tweak this, cap it, upgrade it, whatever. Do not let any process that is not the program the user is actively using eat up any performance! Not by 1%, so certainly *never* all of it!
Apple users are laughing at me for this, fix it! Telling people to go into administrative tools, navigating into tasks and schedules, unchecking settings that are primarily greyed out, is *not* a fix. This is basic stuff!
For some reason I am unable to complete the above steps successfully. In addition, Windows Defender will not turn on, on my computer at all. Why is this happening? I have the current spyware and virus updates as 1.165.4099.0 is this correct? All else seems to be working properly but I have my doubts.
