How to avoid the Windows Defender SmartScreen prevented an unrecognized app from starting warning?

Hi there,

I have code signed my vsto outlook application setup .exe using the GoDaddy code signing certificate. But when the application is downloaded from the internet, I get this message.

 

Windows protected your PC

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

What could be the problem?

Thanks
