I recently downloaded a "fake" Age of Mythology of of Kazaa lite, that was really Empire Earth and that didnt even work. The filename said "Age of Mythology.exe" and there wasnt any inclination that it was a fake IMO. It says "Age of Mythology (real version)" as the title and has quite a few users on it. Just letting you know. This is the only thing I hate about filesharing.
There was a virus on it as well, but it was a weak one that can be cleaned easily with McAffe.
