Windows 10: Windows Defender Scan Interrupted

We have about eighty laptops with Windows 10 and Windows 11 that are all experiencing an issue with a weekly Full scan that we are enforcing with Microsoft Intune which are being interrupted because of activity. We are using Surface Laptop 4s. We are always going to be on them, so there will always be activity. When we are not on them we shut them down.Is there a way to force the full scan to run even when activity has been detected?

defender scans

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.

 

Does Windows Defender Quick scan interrupt Advanced scan?

Before I create a System Image, I run an Advanced scan using Windows Defender, and it typically takes about an hour and the Scan history lists about 4,000,000 files scanned. However, often I see only about 40,000 files scanned, what I get from a Quick scan.

I can think of two explanations that might account for this:

1. The Advanced scan completes, but a Quick scan starts afterwards and wipes out evidence that that the Advanced scan occurred (unless presumably some problem was found).

2. The Advanced scan is interrupted and a Quick scan runs.

Are there other possibilities?

The 2 possibilities listed above are both unsatisfactory because I can tell if an Advanced scan was completed. If an Advanced scan was just completed, there is no reason that a Quick scan should be run automatically.
