I've changed firewalls... now using Agnitum Outpost, very very impressive firewall and a lot easier to manage than Tiny Personal Firewall 5.5 ... but i am keeping a close eye on TPF 6.0 which i have tested on my other Server 2003 install, i believe it will soon join the ranks of mainstreme firewalls due to its ease of use and flexibility.
for my AV i use Nod32 simply the best for me. im not a fan of Norton Bloatware Anything, sorry just had to say it.
btw, i tried McAfee and it slows your system down ... very noticeable during bootup and shut down.
