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. All this power is readily accessible, with built-in assistance that helps you get started quickly and respond to threats effectively. And Symantec's LiveUpdate keeps Norton Personal Firewall current with regular, automatic downloads of security updates to defend against new threats. For small businesses, 5- and 10-user packs are also available.
