Norton Personal Firewall 2003 has robust defenses, including intrusion detection, application control and privacy protection — all in one easy-to-use program. Right out of the box, Norton Personal Firewall 2003 hides your PC on the Internet to keep hackers from seeing it. That action alone can prevent many attacks. In addition, Norton Intrusion Detection thoroughly examines incoming Internet traffic and automatically blocks suspicious activities.
Hackers can also conduct malicious activity from your PC, so Internet Access Control stops spyware and Trojan horse programs from connecting to the Internet. Norton Privacy Control easily prevents confidential data from being sent over the Internet without your knowledge. It protects personal information in e-mail, instant messages and Microsoft Office attachments. LiveUpdate keeps Norton Personal Firewall current with regular, automatic downloads of security updates to defend against new threats. Don't allow your PC and your personal information to be vulnerable on the Internet.
