Minimum security recommendations?

[Nomad84]

I have been away from poker and most security-critical computer activities (accessing financial accounts, etc.) for about a year. I just bought a new laptop a few days ago and I plan to play some poker again starting soon. I have not yet had internet set up at my house, so I'm on my neighbor's open network. I am pretty sure that is bad, so I won't be playing poker until I have a wired connection or my own secure wireless. On my XP machine, I used to run Zonealarm, AVG, and a router. I also ran regular checks with AdAware and Spybot. I am not up to date on the current security software or on what I need with Vista. What would be your recommended security requirements to play poker and access financial accounts on a laptop with a wired connection and with a wireless connection? Thanks!
