I'm looking for the best free firewall for my PC.

What's the best free firewall available, I have looked at so many but don't know what to choose.

Each day, millions of users log onto the Internet. And with the price of services steadily decreasing, accessibility is increasing, which means that more and more people are accessing the world wide web on a regular basis. Even those who may not be able to afford their own service make use of public facilities, such as libraries, to log on occasionally. Just as with any type of technology, the Internet is experiencing growth and development on a constant basis. Along with any growth and development, issues develop that must be addressed. One of the main issues that plagues the Internet is security.

Because there are certain individuals in society who have little or no regard for others, it can sometimes be difficult to enjoy this wonderful technology. However, if you put a few safeguards in place, then your Internet experience can be a pleasurable one for the most part. That is not to say that you will not experiences difficulties from time to time, but you should not leave the door wide open to these vulnerabilities.

You probably already have anti-virus software on your computer and if you do not have any, then you should. In addition to your anti-virus software, another personal line of defense for your system is a firewall. Firewalls are an excellent way to help protect your computer from attack and allow you to enjoy a pleasurable online experience. To understand why you need a firewall, you will need to also understand a little about how the Internet works.

When you are surfing the Internet, information is transmitted in both directions. In simple terms, you tell the computer where you want to go and it returns the information you want. However, unscrupulous individuals make use of this same gateway to conduct their malevolent activities. Having a firewall in place helps to prevent them from accessing your computer and the information stored on it. The main goal of your firewall is to prevent the unauthorized transmittal of information in either direction.

There are a few types of attacks that firewalls help prevent – intrusions, information theft and tampering, and service attacks.

An intrusion is basically just when someone or something is trying to access your system without your knowledge. And once access is gained, then the intruder can cause all types of havoc such as stealing sensitive information, accessing other systems, and tampering with information stored on your computer. This type of attack is the kind most individuals use firewalls to protect themselves from.

Information theft does not even require that the system be breached. If FTP servers are not secure and the software is not up to date, many times attackers use these vulnerabilities to download sensitive files or plant Trojans to complete their job for them.

Denial of service attacks are the attacks that prevent users from accessing the services they desire. Businesses are often the targets of these types of attacks and, unfortunately they are very difficult to prevent.

Some attackers are simply seeking a thrill while others intend you harm. You can prevent these attacks by installing a good firewall, especially if you are using a high speed Internet connection. You can configure your firewall to block protocols and set the level of security you desire. You should choose a firewall that has the ability to block all types of intrusions, control which applications on your computer can access the Internet, and prevent the execution of malicious scripts.

Firewalls are a personal line of defense for your computer and help you to enjoy the Internet safely. Making sure that you have one place is no longer an option, but a necessity.

Zone Alarm is free and does the job. Paid for firewalls just add more features, which are usually worth it if you are concerned. Try it out by testing it at one of many security testing sites eg symantec.

Its a spy-ware removal program.

If you want some decent advice take this.

Buy a router with a hardware firewall, they beat any software one and are pretty bulletproof.

Depends on your system I suppose. If you have an old PC then the advice I was given was to use that as a firewall with, for example, smoothwall which is a Linux based firewall.

I have used Zonealarm in the past and, like the previous suggestion, it is good though free stuff has its limitations.

I would never again use Norton. Adds itself to too many things on the PC unnecessarily.

McAffee you can get as a free disk on some computer magazines and is reasonable.

I have a full suite from Kaspersky, as well as Windows own and that works fine though at $70 a year is quite expensive and there are others that use Kas technology and come in at half the price.

I'm awaiting advice on building smoothwall as a hardware firewall and i'll add more to this post.

ZoneAlarm, you can get it for free.
Outpost is good and works great, but it's not freeware :(

Although a hardware firewall (router) will stomp software firewalls flat, Dave Hybrid said, the best two software firewalls are nod32 and f-secure (they are also antivirus's as a bonus)

Zone alarm is good. I have had no firewall or antivirus for about 2 years now and my computers runs as fast as when i reinstalled windows. I guess the trick is to not download too much porn and to just check what you are downloading. For e.g , You want to download utorrent , so you type it into google , then go download it from somewhere like filehippo. You should download it from utorrent.com . That is the correct way to do it.

So how do you know your PC is clean if you have no Anti-virus?

Answer: You don't.

I love it when people think just because a computer is fast it has no nasties on it.

[Dave Hybrid]

Yup, they're a hackers dream.

My honest opinion zone alarm is one of the best free firewalls and it does seem to do the trick for me and doesn't use up many processes and updates regularly but im not sure really about ones you have to pay for as ive pretty much always have used free ones.

Yer ok ,i agree, my comment earlier was incorrect. Ok i have a lot of anti spyware ,anti virus, etc.. but i dont have them on. I scan about once every 4 months or so and pick up nothing. I recommend if you download a lot that you do keep them on ,but in my case i rarly download and if i do i am familiar with the software website. Zonealarm is good but the full version is better. If you cant afford the full version please email me onand ill sort the full version out for you free. :):):):)

Not on my forum you won't.

You cannot discuss software piracy here or offer it to others, not to mention it's illegal and immoral.

If in doubt the rules are at the top of each and every forum page.

no no , you have it wrong. I am a network administrator at queens college and the school went over board on buying the firewall so i have a couple of copies spare. Nothing illegal. Dont worry
