Norton AntiVirus (NAV), a product of Symantec Corporation, is an award-winning antivirus program available for Windows XP and Vista. It is designed to protect consumers from viruses, worms, spyware, and other types of malware. Norton AntiVirus is sold as a standalone product or included as part of Norton Internet Security and Norton SystemWorks. The latter products add more comprehensive PC protection, including monitoring for spyware, adware, and other potential security risks. Virus definitionsSymantec's Norton LiveUpdate provides virus definition updates, which enable Norton AntiVirus to detect viruses known to Symantec; a total of 73,939 viruses as of March 23, 2008. In order to receive updates, a valid subscription is required; an initial subscription good for one year (or 90 days for OEM copies) 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.Version HistoryVersion 2006 (13.0)
