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?

    After quite some time I found the Idle, Power and Network boxes under the Conditions tab. They are greyed out, how do I change these settings?

    Hello Tadasha,

    I tried this, and I still have the Antimalware hogging my CPU.  When I switch from different applications, it tries to start up, then stops again.  Its like it is still running a scan and won't stop.  I disabled Defender and that didn't work either.  Any suggestions?

    Thanks!!

    I am Sorry to say " Microsoft don't give a *uck! They have been selling Operating systems that don't work since they started!!!! And will be forever!!!! 8.1 has more problems right out of the box, than any other Operating system they have ever come up with!!!!! MAC Works Great!!! Been on a Mac for just over 2 weeks. It has been a learning experience. But so far no problems that I have found with 8.1. But if you ask Microsoft, They will say it will be fixed in 8.2. They always think they are gonna fix it next time!!!!

    What about this time? What about the people that have paid for Several operating systems that don't work right? I paid for every operating system since windows 98!!! No One should feel more ripped off than me!

    What happened to windows ME and windows Vista? They never worked right at all!!! I hope Bill Gates Chokes on all that money!!!!! Any other item I have bought that didn't work right, I could return!!!!

    But Windows is you bought it, Now You have to just deal with it, and wait for a workaround, Not a Fix!!!

    I did not go with MAC in the beginning, because not all programs worked with MAC. But now is different. You would be surprised how many programs work with Mac as well as windows!!!!!!!!!!!!!!!!! Windows has been trying to keep up with MAC. But too many Problems, Too many Workarounds. You have to disable  Microsoft Search Indexing, And Antimalware Service Executable. You can try to disable them but they keep coming back to haunt you!!!!! Bill Gates Is kicked back Laughing at us all while holding our money in his hand!!!!! Look at the EX CEO he has so much money he can afford to spend 2 Billion Dollars for a Basketball team!!!! NEVER AGAIN!!!!!!!!!!!!! I will never spend a another penny on any thing that says Microsoft. Remember Gomer Pyle. Fool me once, fool me twice, but fool me 3 times, And Go *uck yourself!!!!!!!!!!! Bill Gates Needs To Quite Giving Money away to people who never purchased windows and start giving refunds to the people that did!!!!!!!!!!!!!!!!!!!!!! It took me over 15 years to come to this conclusion. But I have been Screwed by Microsoft too many times. Even Gomer Pyle would call me stupid!!!!!!!!!!!!!!!!!!!!!!!!!!! Bill Gates, I am A Disabled American Veteran, Send me some money!!!!! You seam to be giving money away! I can't hardly afford to pay the power bill. And I have been giving you money for years!!!!!!!!!!!!!!!!!!

      Feeling So Ripped Off it isn't funny,

      Muchofreeo.

    you can see, on the right, at Selected Item

    choose Propertiesafter choose Conditions 

    Uncheck all the boxes is ok 

    Disabling the feature is not acceptable.

    Please stop trying to improve resolution rates unless you can link to Microsoft Connect showing us a fix has been implemented. We don't want a workaround that turns off system features, we want them to work correctly.
