If you downloaded the game from the official site and everything, then no, it would not have come with a virus. DBO however, like most games, is detected as a virus by some anti virus software, but the game itself is fine. I think this whole situation was a coincidence. I have never received a virus from downloading the game, and this is the first time I have ever heard of a situation like this. Most people I know who had a virus on their computer because of downloading DBO is because they downloaded the file from an unreliable source.
