What internet security/firewall/virus protection is best for fresh install on laptop?

I am thinking of getting this acer laptop:

ANd it does not come with virus or firewall protection so I am asking the guru's here if I should use AVG and then what firewall? It will have 64 bit Vista on it and I won't want to be online for long without protection, just long enough to download it or maybe download now and burn to disc and install from that. That might be the better way to go.

So I have hear Comodo is a good firewall but I don't know...

What do you think? What will be best? Should I just get their forty dollar internet security suite?

Thanks OFG, I haven't used AVG before but I am hopeful it will do the trick. I have macafee for internet security on the desktop but I want something diffrent. Something better.
