The Symantec support web site states that Norton AntiVirus 2003
is no longer supported. Perhaps you should consider upgrading
to their 2005 or 2006 version.
Please be more specific in your statement. Symantec does not supply
"TECHNICAL" support nor "New" application engine updates for NAV2003
any more but continues to supply updated virus definitions to the 2003
NAV Engine which is the same definition array as used by all later
versions of NAV. At this time, Symantec does not envision ever
denying virus definition updates to any of their older version
application engines. Also, Symantec still offers and will continue to
offer, via live update, the "existing" 2003 engine updates that were
produced during the 2003 era for all those still installing and/or
reinstalling the 2003 engine.
For older and/or slower systems that are sensitive to Heavy Resource
Footprint applications (some call it Resource Hawgs), NAV 2003 is
still a viable option to virus protection and will enjoy continued
virus definition updates from Symantec into the foreseeable future.
