first, Mcafee with Artemis has been certified Advanced+, without it, it only recieves standard certification.
So my answer would be Symantec Norton 2009, or none of the above.
Norton 2009 is good, but has poor heuristic detection abilities
They are both better than AVG though (standard cert). The funny thing is if you want a AV that outperforms both Mcafee (without Artemis), and AVG, go with the free Avast! or Avira Antivir; both are Advanced certified.
As for the firewall leak test I can ace that with Vista firewall/and a hardware firewall- there really is no need for a "security" package, and if you dont feel like configuring it yourself, try the Sphinx free firewall control.
