<edit>Just realised you didn't know how to sort it out either -
Go to Norton Personal Firewall, click on the "Options" dropdown box at the top, then "Norton Personal Firewall". Choose the "Web Content" tab, add your host ("localhost" etc), leave everything at default, but on the "Ad Blocking" tab, add "Permit /" (iykwim), click Ok, and it's all done...
