免费Windows防火墙推荐|推荐一些功能强大的FireWall

      除了windows自己带的防火墙之外，免费的防火墙很多了，国内的天网之流我过去用过后来觉得还是不很爽，换了zone alarm,当然下面了有很多了，请诸位自己选择了。防火墙的作用我就不多说了，主要是防止木马的入侵还有其它人的恶意行为.Online Armor免费版,ZoneAlarm免费版 ,Comodo个人版 ,Privatefirewall ,Sunbelt个人防火墙 ....选择自己机会多，还是老规矩，先国外Windows防火墙后国内Windows防火墙，不是看不起国内的，而是国内确实做得很糟糕的。

1、Online Armor免费版

      这是一款众多技术论坛推荐的防火墙软件，可以有效地防御黑客入侵和网络攻击，而且用户界面都非常简洁。Online Armor支持XP, Vista和Windows 7。不过，Online Armor不支持64位版Vista和Windows 7。 　

需要提醒的是，安装完成后用户还需要注册，而且免费版Online Armor比付费版少了很多功能。

2、Outpost Firewall免费版 

　　这是一款支持Windows 7, Vista, XP和Windows 2000的优秀防火墙软件，用户界面都简洁。 但微软已不再向Windows 2000用户提供技术支持。Outpost Firewall提供输入和输出网络防护，并且是提供主机保护的基于规则防火墙。 不过，免费版Outpost Firewall功能方面存在一定限制，缺少了网络内容拦截和IP地址黑名单功能。

3、ZoneAlarm免费版 

      ZoneAlarm来自互联网安全保护领域首屈一指的Check Point软件技术有限公司，支持Windows XP, Vista和Windows 7。ZoneAlarm提供输入和输出网络防护，反钓鱼功能和2GB在线备份空间。这个防火墙功能之强大，我的最爱，不过要好好用，才能发挥好的作用。

ZoneAlarm Free makes it easy. Unlike other personal firewalls, ZoneAlarm protects automatically from the moment it`s installed – no programming required.

ZoneAlarm Free can barricade your PC with complete and immediate port blocking. And, then runs in Stealth Mode to make your PC invisible on the Internet – if you can`t be seen, you can`t be attacked.

ZoneAlarm Free delivers simplicity without compromising your security.

A getting started tutorial explains controls and alerts to get you up and running quickly. And, to keep you confident that you`re always protected, intuitive color-coded alerts rate security risks – in real time.

For basic, “no frills” firewall protection, ZoneAlarm free is the popular first step for many home PC users. And it`s still FREE for individual & non-profit use.

4、Comodo个人版 　

与ZoneAlarm免费版系统一样，用户可以在Windows XP, Vista和Windows 7系统中使用Comodo个人版。 

Comodo个人版允许用户修改防火墙规则，并提供主动防御功能。安装时，用户还可以选择使用Comodo安全DNS服务。

5、Privatefirewall 　　

Privatefirewall支持Windows XP, Vista和Windows 7。这款防火墙的性能和易用性令人印象深刻。另外，Privatefirewall还提供注册表防护。

6、Sunbelt个人防火墙 

在30天试用期后，Sunbelt就会提供有功能限制的免费版本。Sunbelt个人防火墙可以拦截广告和记录网络运行日志。用户只可以在Windows XP, Vista和Windows 2000中使用Sunbelt。 

目前，Sunbelt还不支持Windows 7系统。 

The web may be free, but we all know that to safely bank online, buy music, software, or books, or even simply surf the web, there is a price to pay. To combat online threats, firewall, anti-virus and anti-spyware software have become essential investments for any home or business computer. These programs monitor and control system access and scan and remove your system of malicious or spying software. 

But the range and sophistication of malicious software and hacking techniques is rapidly expanding and against which traditional software solutions do not provide a proactive defense. Now, Privacyware meets this need with Privatefirewall ― a proactive, multi-layered defense solution for Windows desktops and servers. What's more - Privatefirewall is now absolutely FREE of charge.

7、PC Tools Firewall Plus 

PC Tools支持Windows XP, Vista和Windows 7，其特点是占用系统资源较少。
