When I try to extract the files, it says that is has a trojan in it.
Would you by chance by using BitDefender? It's a known issue (from another player) that BitDefender likes to flag our files as a virus. I suspect it's because some AV softwares mark .exe files that haven't been downloaded much and are relatively new as virus automatically. In any case, we've checked the files with a few antivirus software such as Avast McAfee Norton...etc. and they all came back as clean, nothing detected. So if you do want to play the game, you can disable antivirus for a minute as you extract the files, or otherwise I'm afraid there really isn't another solution. Apologies for the difficulties!
