How to Access Windows Security Protection History in Windows 11

This post shows student and new users steps to access and monitor actions taken by Windows Security App on the Protection History page in Windows 11.

The Protection History page in the Windows Security app is where you can go to view actions that Microsoft Defender Antivirus has taken that includes, Potentially Unwanted Apps that have been removed, or key services that are turned off.

If you need to view and monitor what security actions are taken by Microsoft Defender Antivirus, you need to go to the Protection History page. There you’ll see the latest protection actions and recommendations from Windows Security app.

Events are shown as a series of cards in the protection history. If a card needs your attention you will see one of two colored badges on the card’s icon.

  • Red – This is a serious item that requires immediate attention.
  • Yellow – This item is not urgent, but should be checked when you can.

Protection History only retains events for two weeks, after which they’ll disappear from this page.

If Microsoft Defender Antivirus detects a piece of malware it will be recorded in Protection History under Malware alerts.

Below are the different actions that you’ll find in Protection history.

Threat found – action needed

This indicates that Microsoft Defender Antivirus has detected a possible threat and needs you to make a decision on how to handle it.

When you select the Actions dropdown, you’ll find options to Quarantine or Allow on device.

Threat quarantined

This indicates that the threat has been blocked and quarantined and hasn’t been removed.

There are two actions you can take:

  • Remove – This removes the threat from your device.
  • Restore – This puts the file back on your device where Defender will once again detect it as a threat and create a new Threat found – action needed item in Protection History.

Threat blocked

This indicates that Defender has blocked and removed a threat on your device.

Potentially unwanted apps (PUA)

Potentially unwanted applications are a category of software that can cause your machine to run slowly, display unexpected ads, or at worst, install other software which may be more harmful or annoying.

This app has been blocked

Microsoft Defender SmartScreen has the ability to block potentially unwanted apps before they’re installed and if that happens you’ll see a blocked event in the Protection History.

That should do it!
