Which programs?

[KPJ]

As I'm installing a new rig for everyday use (Internet, gaming, office stuff and so on), I would like to hear, which programs, I should have installed.

I'm thinking, this is, what I need:

Firewall
Antivirus
Office

Something missing?

All the programs should be FREE.
Hope you'll help and recommend some good progs.
