Windows 10: Antimalware service executable using lots of ram

So this has been happening for weeks now. Antimalware service executable keeps using so much ram. I do know that it is a windows defender process but I do not think that it uses this much ram. It keeps using 400-500 MB RAM all the time. I've tried all the other fixes like unchecking all conditions in Task Scheduler and such but none of them have worked. They work for sometime but it goes back to using the same amount of ram. Windows runs a scan few times but it still keeps using lots of ram. I am sure that there is no virus on my PC too.

Antimalware Service Executable hogging up a lot of RAM.

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing high RAM usage issue due to Antimalware Service Executable.



It is one of the background-running services in Windows Defender. Antimalware Service Executable is running to scan the malware and spyware when you access them. It will detect if there’s anything harmful on your PC Aside from that, it also takes a
background scan of your system for any viruses or worms. Its scanning relies heavily on your computer’s CPU, that’s why you find it’s eating the CPU usage on your Windows 10.



To get this sorted, I suggest to follow the steps below:



Method 1:

1. Press Windows key + R, to open
   Run dialog box.
2. Type taskschd.msc and click on OK.

1. Now expand Task Scheduler Library >
   Microsoft > Windows
   
2. Select Windows Defender and on the right hand pane double-click on
   Windows Defender Scheduled Scan.
   
3. Under General tab, uncheck the box next to
   Run with highest privileges.
   
4. Select Conditions tab, uncheck all the items and click on
   OK.
   

Method 2:



Add Antimalware Service Executable to Windows Defender exclusion list.

1. Press Windows + I keys together to open
   Settings.
   
2. Click on Update &
   Security and select Windows Security.
   
3. Now click on Open Windows
   Security.
   
4. Click on Virus & threat protection
   
5. Under Virus & threat protection settings click on
   Manage settings.
   
6. Scroll down and look for Exclusions and select
   Add or remove exclusions.
   
7. Click on Add an exclusion and select
   Process.
   
8. Type MsMpEng.exe and click on
   Add.
   

Restart the PC and check if the RAM usage is high.



Let us know how it goes.

Antimalware Service Executable hogging up a lot of RAM.

I did a clean install of Windows 1903, and I got this app that pops up in my task manager. It's called 'Antimalware Service Executable'. And it hogs up a lot of RAM, I've watched a couple of videos and gone to sites which didn't help at all. I also did
a virus scan, yet it is still there. Any help?
