Where did you buy it?
If it was a legal, boxed, Ubisoft-produced copy in English or one of the other languages Ubi published it in, then a virus is unlikely. If you bought a pirated version, then this is possible. (I'm not suggesting that you knowingly bought a pirated version - people sell them on ebay, and even in stores in some countries.)
Either way, if you think your game has a virus on it, you should contact Ubisoft about it. They do all the production and distribution for this game so if there were a virus on it, that would be something they'd have to deal with.
