My favourite Firewalls !!!

Well, firewalls are basically first line of defense against hackers !!! They are not all , but they surely try their best to prevent un-authorize access to you OS. They can be either hardware or software. Mostly, personal firewalls are of software type , which controls the n/w traffic.
Here are couple of firewalls that I liked, and which are famous among its users....

• Comodo Firewall pro. :- Comodo Firewall Pro is aimed to secure your system against internal attacks such as Trojan viruses / malicious software and external attacks by hackers. Safeguard 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. Perhaps it is the best firewall in free catagory but at the beginning it asks lots of questions and it makes a little annoying and unwated thing.

• Zone Alarm :- ZoneAlarm 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. I think, ZA was the first some of the firewalls that were desinged to use publically free !! Pretty old brand with good name.

• Ashampoo Firewall :- The Ashampoo FireWall makes it easy for anyone to set up an effective, free firewall. Its Configuration Assistant guides you through every step of the the setup process. Easy Mode makes using it a breeze. You dont need any special technical knowledge, and everything is explained clearly. Even with its additional security tools, Ashampoo Firewall is a tiny program that uses very little memory and computer resources. You get heavy-duty protection without a heavyweight load on your system. The Ashampoo FireWall user interface explains itself every step of the way. The information is right there on the screen where you need it so that most users will never need to consult the help files.
