Symantec NAV definitions are not released immediately on LiveUpdate - instead, they are released for manual download on the Symantec website and the LiveUpdate definitions are only updated approx. ONCE A WEEK. This concerns me as many people who rely on Norton Anti-Virus auto-LiveUpdate are not getting the protection until up to 7 days AFTER the viruses are ABLE to be detected. (And millions of computer users have Norton as their only defense...) More, and rather scary, information is provided as a direct quote from the Symantec website: Could anyone explain to me why there is a 133 virus difference between the LiveUpdate definitions and the Intelligent Updater definitions? Doesn't this put many regular computer users at unnecessary risk? Would it REALLY be that much more work to simply put the new definitions on the LiveUpdate server?
