Can't get rid of 1 annoying pop-up

[lmass]

I have pop-ups blocked on my IE7 - VISTA OS. Suddenly, today, when I go to
excite.com and click on a news item, I get a pop-up from:
http://www.yourtopbrands.com/9qw2E61dd8615?sud=11286

I tried to add it to my security blocks but that didn't stop it. I cleaned out my cookies - still pops up. Any ideas?
