Windows SmartScreen helps keep your PC safer by warning you before running unrecognized apps and files downloaded from the internet. If you are downloading an unknown file or opening any potentially unsafe file, Windows will display a warning and confirm before you access the file. If an app or a file has been blocked by Windows SmartScreen, you can unblock it to open it if you trust it.
