Norton AntiVirus (NAV) is a product of Symantec Corporation and is one of the most widely used antivirus programs. The current version is Norton AntiVirus 2007. Norton AntiVirus is sold as a standalone product and is also included as part of Norton SystemWorks. In addition, there is also a standalone Corporate Edition version, which is aimed to a centrally managed corporate environment.
Symantec's LiveUpdate provides virus definition updates, which enable Norton AntiVirus to compete with other Antivirus software. In order to receive updates, a valid subscription is required; an initial subscription good for one year is included with the purchase. When a user's subscription expires, the user can still receive program updates (patches) for free but will not be able to download virus definitions updates without renewing his or her subscription or purchasing a new version of the Symantec product with a year of subscription included.
