I made a program in Python, and exported it to .exe using pyinstaller in one file. I have published it on my webpage in a .zip container (I have tried publishing it bare too.).
When I download it, unpack it, and run it I get the pop-up: "Windows protected your PC. Microsoft Defender SmartScreen blocked an unknown app to start. Running this app kan put your PC at risk" (Translated from norwegian, so maybe not 100% correct to the word.)
Here is the link to the download: https://gerhardadler.no/tetris/ (It is in norwegian, but the only button on the page starts the download.)(This page will be changed or removed in the future.)
Thanks in advance:)
