Trojan warning persists after removal

[cottage]

I'm running Win 10 Pro X64 and Windows defender.

I downloaded a shareware program and scanned it before installing. I got a trojan warning from Windows defender and permanently deleted the shareware program (Shift + Delete). However, Windows Defender still displays the Trojan warning. Even though I deleted the offending program, I asked Defender to remove the trojan but the warning persists.

I then did a full scan with Malwarebytes and it did not pick up any problems.

I have rebooted the computer as well as run a second Win Defender full scan but the problem persists.

I have attached screen clips of the warning as well as a shot of the screen after Win Defender attempted to remove the program.

Any suggestions?

Thank you nasdaq,
I'll do as you recommend but first, I want to ensure that my post wasn't misleading.

I don't believe that my computer is infected with the trojan.

• I scanned the shareware program immediately after download (trojan identified)
• I didn't install the program.
• I deleted it immediately after the virus scan (Shift+ Delete)
• The trojan waring remained in Windows Defender
• I instructed Win Defender to delete the trojan even though the shareware program had already been deleted but the warning remained.
• I ran Malwarebytes and the scan was clear
• I looked at all running applications and services (Task Manager). There was nothing running and there were no suspicious services loaded.
• I looked at task scheduler and there was nothing unusual scheduled to run.

Therefore, I'm assuming that I'm not infected. It's just that Win Defender didn't clear the warning.

Is my reasoning inaccurate?

After double clicking to run Farbar, you say click Yes to the disclaimer. Is this the disclaimer?

Update.....
I deleted the Windows Defender protection history and the Trojan warning has disappeared.

To be sure, I did a subsequent full scan and it is clear.

Hi,

That usually work. The additional.txt that would have been created had you executed the Farbar program would have reported it.

Good work.

I will keep tis topic open for 6 days in case you need to return to it.
