The only firewall I have came with my Windows Vista. And I want to know if that is enough or should I get something better? If I need something better which one? All my software I download from cnet.com and I like “free”. Any suggestions or recommendations would be greatly appreciated. Please take note of what I have by looking at my signature. I am not much of a computer “geek” so it has to be easy to set-up and use. I am looking at Comodo and others which is best?
Hi Para-Noid 
As you are using the Windows Vista Firewall, maybe this article from Stem is interesting for you :

Thank you Rednose for the article, which is very good. I’ve done beta testing with Stem. If you look at my Signature, I use Avast Free, but you can also use Online Armor Free and layer your protection.
As was suggested I believe in a previous thread, I would get rid of Ad-aware and replace it with MBAM which has higher detection rates free http://www.malwarebytes.org/ (the blue button).
The key to security is to layer your software so you are not causing conflicts or over kill. Therefore, I suggest that you trial what ever FW software to see how you like it and how it plays with your other software; not all software play well together.
You can also try Comodo
Hi Para-Noid, i would suggest doing as SafeSurf has mentioned. If you dont want the full avast suite which come’s with a firewall then online armor is an excellent choice, very intuitive and strong with a great hip’s.
In my personal opinion:
Comodo
Online Armour
Outpost Firewall Free
Personal Firewall Tests & Results. Firewall rating:

Comodo firewall is dam dam good You will get more than just a firewall:)
Plus a lot of problems. 
For Vista Windows 7 Firewall Control works quite well:

Second choice would be Outpost Firewall Free
I haven’t had any problem YoKenny
YoKenny don’t start flaming this crap about Comodo I’ve had enough their has been no problem in the latest v5.0, however Comodo has admit their was a minor mistake in v4.0 which has cause a lot problem in MOST computers not all of them and it all depends how the user installed Comodo correctly and the settings. The latest version hasn’t cause any problems so far because Comodo had more time to resolved a lot of issued before v5.0 came out, so it okay to install Comodo ONLY the firewall package not the Comodo Internet Security package.
Thanks SpeedyPC
As a free stand alone firewall Privatefirewall is a good choice. And paid Online Armor Premium
Greetz, Red.
I’ve been using Comodo firewall with Avast for over 1 year, and I am more than happy. No problems at all.
For me, I am really satisfied with avast!. ;D
avast antivirus or AIS (antivirus + firewall)?
I think the OP is looking for a free firewall.
PC Tools Firewall Plus version 7 is free and light on resources.
