iPad and iPod virus?
Okay, I think I've tracked this one down. It isn't a problem with your iPod or iPad, it's a problem with the router itself. Its DNS has been overwritten so that it randomly (about 5% of the time) will redirect you to one of their sites.

Because you're using someone else's open access point, there really isn't anything that you can do about it except to stop using that particular router.
