Windows 10: Trojan:Win32/Stealer.ER!MTB Remediation incomplete

Hello,a few days ago i mistakenly double clicked an istallation file called "SETUP", and then windows defender notification suddenly popped out and says "Trojan detected" or somewhat else. when i click on it windows defender shows the history of this protection.is it real trojan or its just a program that mistakenly detected as trojan? and i don't remember if i ever downloaded the file. then if its a real trojan how to fix it?

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.

 

Windows Security Protection History-remediation incomplete

I went to a website on Edge chromium. The was an audio message saying my computer was locked. It turned out it wasn't. I closed the browser, and opened Windows security. Two trojans were listed in protection history as severe - status:failed - remediation
incomplete. A further scan by malware bytes revealed no threats. The two trojans were Skeeyah.A!rfn and FakeAlert!MSR

 

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,
Jerry
