Theres no way there are viruses, I have been using that program since october and I have had no problems with it at all, I don't know why it would have a virus. Scan it.
(I should have put that when I put up the post, because no matter what you should always check downloaded programs. I always do, even if it is from a trusted source.)
Sorry if you have had any problems with this, I don't know why there would be a virus.
