Do you understand what a firewall really does? Most people would tell you that a firewall protects you from hackers out there on the internet. They’re right, but there’s a little more to it.
Every modern operating system has a firewall. Windows PCs are a special case, because they are specifically targeted by the dark forces out there. That’s mainly true because of the huge user base of Windows computers around the world.
Your firewall is meant to protect you from evil computers trying to access your computer without your knowledge (inbound protection). However, good firewalls also prevent your PC from broadcasting your private information or spreading worms, viruses and spam to other computers (outbound protection).
Many years ago, Windows shipped XP without any firewall protection turned on by default. That was a huge mistake and millions of people paid the price for it. The mistake was fixed by XP Service Pack 1, but many of us have never forgotten what happens when you don’t use a firewall.
Back in the days of Windows 95 and 98, I used a firewall called ZoneAlarm, because Microsoft didn’t even offer one at the time. These days, the Windows firewall for XP, Vista and 7 is adequate, but it doesn’t offer very good outbound protection. That’s why it may be a good idea to try out the newest ZoneAlarm Free. Here’s what the folks at ZA say about their product.
