Better yet, just go out and get a Belkin 4-Port Gateway Router for Cable/DSL and hook your modem up to it. Most routers come with NAT ( Network Address Translation ) and for about $39.95 with rebates, you will be able to HIDE your IP address from any website that you cruise to, and it will prevent pop-ups from occurring.
I installed a Router last month and cut down on my pop-ups by 99%.
