I just got a new laptop. I am wondering what everyone uses for a firewall and what everyone would recommend. I'm thinking of going with the free versions of Sygate or ZoneAlarm.

I use Norton Internet Security on my desktop. How do Sygate and ZoneAlarm compare? Is there an Ad Blocker feature such as Norton has?

Any other suggestions would be welcome.

Also, a recommended free antivirus program? How is AVG Anti-Virus (can be found at www.grisoft.com) ? I have Norton AV preinstalled, and I use it on my desktop, but I'm looking for a free alternative.

Thanks.

And no, I don't want to d/l from p2p.
