An additional instruction to your fix is that the SETUP file for 1.7.2893.0 Beta MSI was causing the continuous errors from Defender. The install file needs to be deleted from you system in addition to installing version(1.x) AxCrypt-1.7.3233.0-Setup.zip. Full scan choked before I deleted the install file despite deleting my old running version. After deleting the old install file itself, full scan finished cleanly.
Again, thanks for the help
Another tip for those wanting to CLEAR the MSFT Defender Protection History is to simply delete the files in folder C:\ProgramData\Microsoft\Windows Defender\Scans\History\Service. I saw the tip to delete the folder itself, but it is protected and can’t be deleted. All but one file in the folder CAN be deleted.
