I don't think NOD has a free firewall though.
Actually, all I really need is something that allows me to control what uses the net on a per application basis.  Not too interested about security, so a free basic firewall which doesn't have a lot of features should be suffice, like the free Outpost one.

I recall used to running ZA on my really old 533MHz computer before - maybe it's now bloated with all the stuff they're adding in I guess?  The free firewall shouldn't have most of the poo poo though, not compatible with Win7 however.
