Diner dash game won't start after installatio

Hello, I installed diner dash hometown hero game, cd-rom software, that I purchased yesterday. While installing a virus warning sign came up, says trojan. First I tried to deny access, next ignore, then send to quartine. I have installed this game 3-4 times by now, trying something different each time. It seems to install okay, then I have to restart the computer, and the game will not start up. Any help will be appreciated. Thanks Cheryl
