Automatic Unattended Updates Possible on Recent Norton AV products?

[PeteF]

Concerning Norton Anti-Virus or Norton Internet Security, in the 2005
or 2006 versions, does anyone know which of these versions can
be setup to automatically download & install the updates unattended?

FYI: I'm writing a FAQ on the topic of Anti-virus programs that I'll post
here. but first I need to know about this update issue on the Norton
products. To my knowledge, 2005 version can't be set for unattended
automatic updates but I'm not so sure about the 2006 versions.

Norton 2006 AV will automatically update and the only thing I see is a small popup window that tells me the AV was updated. It pops up for about 10 seconds and then is gone.
