Windows 10: Defender anti-virus shows "Remediation Incomplete"

Windows Defender shows "Remediation Incomplete" when removing trojan. A screen shot of the error is shown below.When I run a backup, Windows 7 version, I get an error that says that the image file cannot be created because it contains a virus. Any suggestions on how to proceed to get this trojan off my machine would be appreciated.

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 not able to remove that virus. Plz help how to remove it.

I already run
Microsoft Safety Scanner (64-bit). But virus still in my pc

Now Defender shows remediation incomplete Severe

 

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.
