Seems to have spawned from the skyscraper ad on the shop page, but I'm not certain.
The URLs associated with the Blockkeeper page that takes over are:
http://piclie.com
http://birdpel.com
When I hit back, the ad was:
http://media.markethealth.com/ads/1248113634xwomen-provillus-120x600.gif
http://www.provillus.com/?aid=852176
but I do not believe that your system preserves the ad when you use the back and forward button, correct?
