I bought Port Royale 2 and tried to install it. But during the installation I received the message that DR/fakepic.gen was found and isolated.
Why does PR2 try to install a trojan? Did anyone have the same problem (and found a solution)?

Thanks in advance!

Two choices: Either your computer was infected and something attached itself to the game files OR it is a false alert and you need to make an exception in your AV.
