Yes, it is. As soon as you install it, it will delete System32, send a hitman to your house, and destroy your PC. No, it's just a Python wrapper of a .html file of Eaglercraft that I compiled using Pyinstaller (It's not signed so it'll trigger a "We just protected your PC" thing but it's not. If you are still wary you can test with a anti-virus app, I recommend something like Virus Total as it's free and you can scan files.
