Since it doesn't look like there are ads running at all in here.. sounds like you might have a piece of SpyWare running on your system that is popping ads while you are browsing the web. I had heard that there was a version of Morpheus that would drop a piece of software onto your system that would do just that.

Might want to look into downloading a removal/checker tool for that kind of thing (if you haven't already done so)... LavaSoft has one called AdAware that is probably one of the best ones out there.
