That's a false positive, it happens pretty randomly. If you look up "IDP.Generic" virus reports you can find articles about how some Python (the programming language we use) files end up being considered threatening when it's not dangerous, if that helps it seem less worrying.
All I can suggest is that you turn off the malware while installing and playing, looking up to see if there's a way you can tell your malware that you trust the file, or checking to see if your malware is in need up an update. I hope you're able to get your virus scanner to stop with that.
