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?

    Not an option as a malware program is necessary. What is needed is a malware program that does not hog up the disk.

    *Sigh....* Just disable the entire malware program altogether and it won't bother you anymore.

    You are not alone!! I tried every thing suggested in this thread and still have the same problem. I gave away my computer to one of my friends. He used it for just over 2 weeks, and gave it back to me. He said it is still starting up when he starts the computer and when he uses WinRAR. He said it almost totally disables to computer when it starts. No telling how long it will run. Sometimes 5 minutes and sometimes 3 hours. Bill Gates Are you reading this???? Your NEWEST **** Operating System is broken!!!!!! Fix It!!!!!

     Feeling Robbed,

     Muchofreeo.

    Yip - I was able to do this but this feature is still slowing down my computer and unchecking these boxes did not help.

    What I find particularly unhelpful is that, in order to get to a useful answer, I have to read through loads of complaints and unhelpful patronising comments from people who think they are smarter than everyone else!

    I went through the same issue.  What I found is that if you start messing with these buttons and you have some actual malware it was trying to delete, it gets stuck in some type of loop and doesn't stop.  It continues to execute the task.  I looked in my web add-ons and found some coupon thing I didn't download.  I removed it, and the problem went away.  Good luck!!

    Excuse me? The fact that I think I am smarter than you has nothing to do with this, but you have proven me right at every turn so far. Moreover, I didn't imply that at all; I implied that you are lazy. I have pointed you straight towards the answer after which you were still incapable of finding it in just 4 pages of the thread you are already on. So I searched the thread for you, found the answer 3 times in under 2 minutes and copied the it. Now instead of a 'thank you' you start talking back to me?

    Who the **** do you think you are, expecting others to search the forums for you to give you the answers you seek on a silver platter? This thread isn't just littered with loads of complaints, but with several people asking the exact question you did, all of which have received the exact same answer. You are part of the very problem that bothers you so much

    Finaly, yes, I also know a solution to your other question, because I posted it in this very thread. It's probably not the answer your were looking for, though. You can either search for it yourself or, if you are too lazy, kindly ask me on which page and see if I'll reply. Just don't assume I'll go and fetch it for you again.
