Oh.. I think you're talking about the BLINX Ad.. Or something like that. Hmhm..
I thought it is really an advertisemnet coz I also experience this in [url]Loudfusion.com[/url]
Anyway, when I'm using Firefox I have this extension called "AdBlock Plus" and it blocks all advertisements.
Though it's not a good idea because some sites can't gain money for removing their ads.
Well, that's only for Firefox. What about for IE?? Uhmm.. I believe that there is also a program that upgrades your IE.. Called "IE7 Pro".. It has many good stuffs in it like Ad Blocker, Dload manager, Crash Restore and the likes. Haha.
It's up to you
