>>As you say, there are always those who will allow access even though they know they haven't done an update. It's one of the reasons I won't allow anything on my system to do automatic background updates.<<

I wholeheartedly agree. I actually resent systems that "assume" it's ok to "call home" for updates and even to install them without asking first. That's one of the main reasons I like Zone Alarm Pro: I can configure it to notify me when these ill-behaved programs start such antics.
