windows defender runs slow

Hi Thomas,

Thank you for posting your query in Microsoft Community.

I understand the inconvenience you are facing currently. Let me help you in resolving the issue.

I would appreciate if you can provide us the following information to help us understand the issue better.

• Have you installed any third party security application in your system, apart from Windows 10?
  
• What is the make and model of your computer?

I would like to inform you that this issue might occur, if the Windows defender is scanning too many junk or malware effected files in the system. As of now,
I suggest you to run System maintenance task and check if it helps.

The Run maintenance task checks issues that might slow down your computer's, such as how many users are currently logged on to the computer and whether multiple programs are running at the same time.

Follow the below steps.

• 
  Press Windows + X on the keyboard.
  
• 
  Select Control Panel.
  
• 
  Select Troubleshooting.
  
• 
  Click on Run maintenance task under
  System and Security.
