Windows 10: Windows Defender Slow Scans on an Intel I7 Desktop

Hi All

Issue is Defender scans really slow, like over 12 hours if I choose to do a full scan, Previous was Avast that was removed with the tool, Malwarebytes 3 Free, Is it cause I use the configure defender x64 utlity to up the cloud protection level and such

Any advice appreciated

:)

 

Windows Defender - Very slow scans


That's pretty strange. We all know laptop harddisks are usually slower (5400rpms) but 3 hours is an insane time for a quick scan. Can you check process manager to see if there is anything else running that is slowing things down?
On my desktop i7 (SATA II hd), Defender takes about 5 minutes for a quick scan.

 

right click scan in windows defender?


thanks for that.. i didn't notice the tutorial section :x

I did the suggested registry change and it's now listed on the desktop context menu.. but all this does is ask if I want to open it, update, or start a scan... I was hoping for the option where you right click a specific file and it will have listed 'scan with windows defender' like other antivirus programs have.. MSE had it. I'll keep looking around to see if I can find it in the meantime..

Hi Ian,

Thanks for posting your query on Microsoft Community.

This issue might occur if you have set any task scheduler for Windows Defender.

I suggest you to delete the task for Windows defender and check if it helps.

Follow the below steps:

• 
  Search and open Schedule tasks.
  
• 
  In the left-hand menu, open the Task Scheduler Library, then select
  Microsoft >Windows >Windows Defender.
  
• 
  Double-click Windows Defender Scheduled Scan.
  
• 
  Select the Triggers panel, then select Delete.
  

Hope it helps, reply to us with the status of your issue. We will be happy to assist you.
