Downloading Symantic Live Updater?

I have Symantec Endpoint Protection and the antivirus/spyware protection is apperantly out of date so when I try to fix the problem i get an internal error report and that i should reinstall live update. Well i cant seem to find where to download it cus it would seem I deleted it a long time ago. So does anyone know where to download Live Updater because when I search for it on yahoo i get 3rd party downlaods and i dont trust those. any help thanks.
