Windows 10: Remediation Incomplete, Status: Failed after quarantine attempt. How to make sure threat...

I received an alert from Windows Defender that a trojan had been found. the actions available to me were “Quarantine” and “Remove”. I chose quarantine, and after a couple of minutes I was told “Remediation incomplete” and “Status: failed” But I don't have the option to try removing the threat or doing anything else.I did a full scan, which didn't detect any threats. How can I be sure the Trojan has been removed?

Windows Security Protection History-remediation incomplete

Windows 10 security found two trojans that are now listed in my protection history as severe-remediation incomplete. And yet my virus and threat protection shield icon has a green checkmark. What if anything should I do? Why does it say remediation incomplete?

A manual scan by Malwarebytes identifies zero threats.

 

Remediation Incomplete Message

Remediation Incomplete Message

I had a Trojan threat that indicated a virus was in Temporary files. I ran CCleaner to clear temporary files. I then checked Windows Security and it said my Virus and Threat Protection was ok. See screenshot.

Later, I rechecked Protection History and found the Remediation Incomplete message. See screenshot. I read that sometimes this message can appear after clearing a virus threat.

I ran CCleaner again and also Malwarebytes. I also did a Full scan on Windows Defender. In all scans they did not show I had any virus issues.

So, how should I treat the Remediation Incomplete message?

Thanks,

Windows Defender is missing Restore Button for Quarantined Threats

It wasn't listed under "Quarantined Threats", but was listed in "See full history" as quarantined. It has been about 2 hours
and now it is listed under "Quarantined Threats" which now shows the Restore or Delete options. Something must be causing
a delay in listing the quarantined file under "Quarantined Threats" after they have been found and quarantined by Defender.
