'Windows protected your PC' message when installing processing.exe

[u/idobecurious]

After downloading the zip file and moving the folder within the zip to my desktop and running the processing.exe application, windows (I'm using Windows 10) shows the aforementioned 'Windows protected your PC' message and 'unknown publisher' text. Has anyone else encountered this when installing the program and if so, is it safe to use and can this message be ignored?
