All firewalls can block incoming access to your computer, but not all provide the level of two-way protection that Norton Personal Firewall (NPF) can. This app offers relatively simple installation and setup and protects systems from both incoming and outgoing connection attempts.



It not only keeps Web sites and hackers from accessing your system, it also won`t allow viruses or any other programs to access the Internet without your knowledge. Unfortunately, NPF is a bear to configure, so we recommend it primarily for technically savvy folks who know their way around a PC and need detailed security settings.



The new version protects confidential data in e-mail, Microsoft Office attachments, Web sites, and instant messages and blocks banner ads and pop-up and pop-under windows off your screen for faster Web browsing.
