I can assure you that there are no viruses on the file. And A LOT of people downloaded it before you.
But I don\'t know what kind of internet connection you have. If you have 56k or something similar, I wouldn\'t download it and wait for the next version, coming soon.
Keep in mind that both the game we have now and the newer versions are only techdemo\'s, and although there is a bit more to do and see in the next version, it isn\'t a real game yet.
