Where to get free firewall?

The firewall that came with my windows xp slows down my computer.
Is there any better firewall that I can download and use it for free?

Re: Where to get free firewall?

Most of the software that was freeware has gone to a license or subscription plan - others are crippled.
There aren't many free firewall programs left for Windows.

NetDefender is a free firewall program that comes with source code. This is about as basic of a firewall as you can get. This package will mostly appeal programmers that want to know how firewalls work. I would not consider this a full blown defense package for your computer.
NetDefender Firewall is completely written in VC++ 7.1 (Visual Studio 2003) using MFC , Windows API, Filter Hook Driver (Provided with Windows 2000)

Download the source code : download

Comodo Firewall Pro is aimed to secure your system against internal attacks such as Trojan viruses / malicious software and external attacks by hackers. It also safeguards your personal data through a simple user friendly single click interface offering full immunity to attack.
Comodo Firewall Pro helps you connect in a secure way to the internet and global networks.


The program still provides a smorgasbord of information and options for advanced users, but it's simple enough for beginners, and runs smoothly and silently in the background.
The most obvious new features include support for Windows Vista at the expense of Windows 2000 support, although the older v2.4 with Windows 2000 support is still available.

Re: Where to get free firewall?

The most widely used free firewall is ZoneAlarm-Download
  • It is designed to protect your DSL- or cable-connected PC from hackers.
  • This program includes four interlocking security services:
  • a firewall, an application control, an Internet lock, and Zones.
  • The firewall controls the door to your computer and allows only traffic you understand and initiate.
  • The Internet lock blocks Internet traffic while your computer is unattended or while you're not using the Internet, and it can be activated automatically with your computer's screensaver or after a set period of inactivity.
  • Zones monitor all activity on your computer and alert you when a new application attempts to access the Internet.
  • Version 7.0.483 is a bug fixing release.
  • An effective and easy-to-use firewall program, ZoneAlarm does a great job of keeping your PC safe from a variety of threats.
  • ZoneAlarm uses a simple wizard to make configuring a firewall, which seems like a daunting task to many computer users, incredibly easy.
  • Maintaining and updating settings also is a snap when you're using the stylish interface and its simple slider controls.
  • The program's Zones feature allows you to assign different security levels for a local network and for the Internet.
  • A great recent addition is small but quite helpful.
  • A new "Game Mode" lets you automatically allow or deny alerts when you're in the middle of playing a video game.
  • ZoneAlarm is an excellent firewall choice for just about any average user.
