Ho do I do that. Just installed Norton antivirus 2009. I did full scan all was fine but it says anti virus definitions are not up to date. specifically said NAV Engine, NAV Resources, Norton 2009 and Virus Definitions, NAV Resources failed to complete. Dont know what to do if I have to do anything at all. Says antivirus is seure. Says firewall and automatic updates on virus protection out of date (isnt that what I just put on Norton 2009)thanks
