Unless you're getting a different popup than I am, that's a youtube video (DD AR-15 ad). If embedded youtube videos freak you out, you must not surf the web much... they're everywhere.
If you have popup blocking enabled, you shouldn't even see that pop-up window. Doesn't IE8 come with popup blocking enabled by default? Tools -> Popup Blocker -> Turn on...
