Cannot start application when downloading app from internet

I was testing the click-once deployment of my app, but am not using a code signing certificate. I would launch the app from the start menu and could see the checking for updates window, but then nothing.

Turns out that Windows Defender was blocking the app, but I wasn't getting any notification at all that this was happening. This was however not an issue a month ago where Windows Defender would show a warning even if we updated before the application started. It seems like this could be a bug in Windows Defender. After the last windows update KB my clickonce app has stopped working.

After that, a message from Windows Defender SmartScreen has appeared so we've been able to allow SmartScreen to execute the aplication. This message didn't appear when the application was executed from the programs menu. Ask a question. Quick access. Search related threads. Remove From My Forums.

The applications that run in the Internet zone sandbox do not have to have the full permission to these security groups.
