If people from here are getting popups from the MP that means they could also have a Trojan already embedded in their system or a worm from a previous site and didnt look in their system folders to clean it out. Popup banners lead to browser hijacking, which will, in turn, place trojans & worms on your machine. Norton wont always catch it. If you got caught and keep on experiencing popups on certain sites that don't have em then you will need to cleanout your computer. Virus software doesn't always prevent your browsers from being hijacked especially in IE. No virus software catches everything that's out there.
