During installation, you might see a screen saying "Windows protected your PC".

What is this?
SmartScreen is a Windows security feature. It automatically displays a warning for apps with low download counts or apps that don't have a paid "code signing certificate." It does not mean a virus was detected.

You can then proceed with the installation normally.
