Windows 10: Windows Defender Protection History

Recently, Defender notified me my computer had the Trojan virus. I went to Defender to do a scan and to get rid of that. After that, I did a full scan. Now, when I go to Protection History, it keeps crashing. I don't know whats happening. Someone help.

Clearing Windows Defender history

Hey, what you need to do is so simple, just follow the steps below exactly in order:

1. Turn OFF Real-time Protection
2. Turn OFF Cloud-delivered Protection
3. Go to this folder C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service
4. Delete the contents in the folder
5. Turn ON Real-time Protection
6. Turn ON Cloud-delivered Protection

That's it... Now check protection History, it's empty.
Done!

 

Windows defender protection history is missing

Hi, have you had any other help yet?

I have another suggestion, check under filter to see what’s set, if there’s a show all then select that.

See if anything is listed under here:

C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service

Defender will automatically remove entries after 30 days anyway so unless you’re checking regularly there may be 0 entries shown due to this.

 

Windows defender protection history is missing

Anecdotally, I have found that when I am using a third-party antivirus (Avast), my Windows Defender protection history is blank. Even when there are detections made by Windows Defender scans, they will not show up there. The only way I can see them is to
look in Event Viewer: https://docs.microsoft.com/en-us/wi...rus/troubleshoot-microsoft-defender-antivirus.
After disabling Avast, protection history is restored.

Although this is my experience, I haven't been able to find any documentation on this behavior, so YMMV.
