Windows 7: Comodo.

I was recommended to get Comodo Firewall for my computer, since ZoneAlarm was found to keep freezing up my computer and a resource hog. Now that I was recommended Comodo, should I use their AV and all their other products for security? Are they good? I have Microsoft Security Essentials, but I prefer sticking to one company.

I do not use third-party firewalls, personally. I use the built-in Windows Firewall, combined with MSE.

So far, I have been protected. No viruses or other attacks.

In answer to your question, it really doesn't matter if you use both a company's firewall and AV. Use your favorite firewall and favorite AV.

I recommend sticking to MSE, because we know it works very well.

I guess I'm going to just use Comodo Firewall then. I don't use Windows Firewall because I tell it to block this program, but apparently, it doesn't. I like something that shows a ZoneAlarm when a program attempts to connect to the internet. My Firewall isn't basically my use for viruses or security.

That's completely fine. Go for it!

By the way, since you are using a netbook, you are accessing from a router right? I believe that routers have a hardware firewall. Why use a software firewall, if you have a brick wall already being your router? =)

I never really like to install third party solutions if microsoft already has one. I find them to be horribly inconsistent.

To prevent applications or spyware from unknowingly allowing access in.

I don't use 3rd party firewalls either but some people like having that extra layer of protection there.

Plus most routers aren't great firewalls. Sure, they are better than nothing, but it is a good idea to have either a dedicated hardwre firewall, or even the Windows Firewall.

Completely true, just that on a netbook, if you want the best performance, go with the windows firewall. If you truely want another third party solution, know your consequences. Though, if you take your netbook to public locations to access the internet, the use of a firewall is integral.

I believe that you should focus on what you have, not on what you don't have, in this case, if you have a router firewall, or windows firewall. The less you have, the more, performance wise. Adding more security is in my opinion not a good sacrifice for performance.

It is your choice of what firewall to use,though I would definitely recommend only a router firewall and windows firewall for best performance and security ratio.

Cheers!

Windows Firewall blocks everything by default (inbound) IIRC. There's no need to tell it to block anything. It will prompt you to allow a program that wants to be added as a firewall exception.
