Windows 10: 35 HOURS for a Full Windows Defender Scan??

Windows Defender is telling me it's going to take an estimated 35 hours to do a full system scan. Certainly this isn't normal..

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.

 

Windows Defender - Quick Scan

Windows defender no longer offers a quick scan option.

My options are:

• Scan
• Advanced Scan

• Full Scan
• Custom Scan
• Windows Defender Offline scan

Whichever option I check, the scan will need to run for hours to complete.

Is a quick scan available?

How do I restore this feature?
