How do you know that it was a virus? What are you seeing that isn't normal?
By 'every time I tried to launch the game it was infected by a virus', do you mean that when you tried to launch the game, you got a popup from your Antivirus?
I had a popup from Windows Defender, it happens when a program doesn't have a verified author. As long as you trust the application you can go ahead and run the program.
What do you mean by 'I went to break and corrupt my system'? What did it break? Please elaborate.
