Hi, This is Ramesh.
Due to a bug in Defender, threat notifications for old and remediated threats may appear repeatedly. If the offending file has already been removed, use this batch file to clear the Defender threat history.

Restart Windows.
*Alternatively*, boot into Safe mode and delete the following folder:
C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service\DetectionHistory
Start your PC in safe mode in Windows - Microsoft Support:

In Safe mode, do this:
Open an admin Command Prompt (CMD.exe instead of PowerShell) in Safe mode.
Run this command exactly as given below:
rd /s /q "C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service\DetectionHistory"
If the threat notification continues to occur, please post a screenshot of that dialog.
