If someone can help me with this I will be eternally grateful.

I keep getting these goddamn page unders that when you try close them they ask if want to navigate away from the page, if you close that out it navigates to another page effectively creating a mouse trap feature and then of course that page can't be closed out either.

This first started on bittorrent index sites but now Latimes, London Times and other legitimate sites now feature this annoying advertisement. It is not a virus I have Norton up to date and I sandbox everything.

If there's anyway this "feature" can be turned off I would be in your debt.
