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?

    Hello. Yes Windows Module Installer some times runs for a few hours after taking updates or installing a program. But it Rarely pulls more than 18% of the Processor. But this Antimalware Service Executable wants to Pull between 75 - 90% of the processor. I just can't figure out how Microsoft can Justify this. I renders both of my computers USELESS when it is running. That is like Microsoft saying WE Own Your Computer!!!!! What is up with that? I will say it again" Microsoft WAKE UP!!! Release a Hotfix for this Screwup!!! My room mate works in a Computer repair shop. This is the Number 1 Problem that people bring in 8.1 computers for to be fixed!!!! So Far there is no fix for it!!! Several people on this site and on this thread act like they have the answer. But they are Lying through their teeth!!! If you try to shut it down your computer Cuts Off!! And all the steps that people say try don't Work at all. When this little **** kicks in, it's like the ever ready bunny, it just keeps Running and Running! I just walk away, and go use my girlfriends MAC!!! It's all I can do. If I restart it just makes it run longer!!!! Again "Microsoft Wake UP, we are all waiting for that hotfix for this 1". I think Microsoft thinks it is protecting the Operating System, But all it is doing is slowing everything down to a SNAILS CRAWL!!!! It still allows people to install **** like Savings Bull And Spigot Bullcrap, which is Parasite Tagalong software which Kills Windows 8.1. This **** if you install enough of it, the only cure is to Reinstall Windows!!! So Antimalware Service Executable is Really No Help At All!!!!!!!!!!!!!!!!! One More Time " Wake Up Microsoft, and release a Hotfix that will Work" after all isn't Microsoft the update king of the world!!!!!! Microsoft Don't let Team OS make you look really Bad!!!!!!!

    They seam to be coming up with fixes faster than Microsoft, that Wrote the program!!!! What's up with that????????

     ****,

     Muchofreeo.

    Well issue I had both processes hogging CPU and disc, but windows module installer worker was worse of two. It was not pulling 18%, but rather 40% and up. Until I went in and stopped the " windows module installer worker" service I could not do anything. Period. Hopefully this was just case of an update gone wrong or corrupted.

    You can "ungrey" enable it by clicking on the Properties link located at the right hand panel. The properties window will appear where you can do your change.

    On the bottom right corner under selected items is a "properties". Click on that and then under conditions you should be able to uncheck power now.
