My company distributes an installer to customers via our website. Recently when I download via the website and try to run the installer I get the warning message:

Windows protected your PC

Windows Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk.

If I right-click on the installer and choose Properties I note the following:

Enter image description here

Our installer is signed.

How do I find the reason for the Windows Defender SmartScreen warning?

I have not managed to find any log file for Windows Defender nor found anything in the Event Viewer.
