AVG. I have it installed on even my Vista computer (the gaming one) and it works nicely. Not a system hog at all, very quiet, but very good.

NOD32 :D mainly cause its light weight, simple and very powerful,

used to use AVG, but stopped using it as its performance started to slip...

Avira and COMODO (firewall pro)
both work fine, detected more then my previous Norton installation and they start up within 5 seconds

AVG/Nod32 are great, I like the mcafee firewall but its VERY controling of your computer.

I use avast, it works great and automatically updates without nagging me or interrupting full-screen apps. It doesn't slow down my Vista PC either.

I've used both McAfee and ZoneAlarm, and both seem to be quite good. I'd say that McAfee consumes more system resources, but that ZoneAlarm has more annoying alerts. I've also noticed that ZoneAlarm has picked up a few things which McAfee didn't.

I'd say that ZoneAlarm is probably my favourite out of these two. I haven't tried any other firewall/anti-virus/anti-spyware software, so I don't know if there is something better out there.

NOD32 for the win. Very thorough scanning and low resource usage. I would recommend version 2.7 over 3, as 3 is very new and has not yet had all the bugs ironed out.
