Tomkitten, your Norton, Adaware and Spybot should be working no matter what browser you use, but , none of the 3 will block popups.
You can purchase software that will block those pesky buggers:

I use Crazy Browser. It's a browser that automatically blocks all popups and ads and it's free

If like Walter you want some of the ads, it can be configured accordingly.
The interface of Crazy is based on the Internet Explorer interface.
