I'm sorry about that! The game certainly isn't malware, so I'd have no idea where to even start to fix something like that. If you have a Steam account and an email I can give you a Steam key for the game. Maybe that won't be effected by Bitdefender.
Thank you very much! Sorry if I implied that I think the game has malware, I'm certain it was a false positive. My email is boldlion.orroaleuna@gmail.com Again, thank you!
