Vista Compatible Firewalls and Anti-Virii?

[WantoN]

Hey guys,
As title I'm looking for a (preferably freeware) firewall and anti-virus for a friend. Needs to be user-friendly, low-rescource and require little configuration. Needs to be vista compatible.

*please note my vista experience is non-existent.

Cheers,
Ant
