Agnitum has released Outpost Firewall, a FREE, powerful personal firewall for Windows. Outpost Firewall gives peace of mind from any threats by cookies, banner ads, e-mail viruses, backdoors, spyware, crackers, adware, and virtually every other Internet danger. Unlike other personal firewalls, Outpost starts protecting against all kinds of internal and external attacks as soon as it's installed. This is the first firewall with an open architecture and support for plug-ins, so its capabilities can easily be extended by thousands of developers worldwide. Outpost protects your system from worm and virus attacks that arrive by e-mail. You can filter e-mails based upon their content, and Outpost will prevent dangerous attachments from executing. Outpost performs web filtering, allowing parents, educators, and businesses to exercise control over the content that is allowed to reach your computer. There is a privacy guard feature, as well as a plug-in that will block banner advertisements from your web pages.
