There's an option to get notified every time 'important' updates are available.
ahhh, yes.... the first time i got such a notification, i was furious that they had "invaded" my system... so i hunted down the option and turned it off!
tend to now always look at options on new software, and change preferences to "manual" update... especially for anti-virus software (after having seen it turned off by a virus at the office a year or so back... <img src="/ubbthreads/images/graemlins/rolleyes.gif" alt="" /> )
mind you, other than IE, Opera and SETI @ Home, my firewall doesn't let anything in or out without asking permission. <img src="/ubbthreads/images/graemlins/badsmile2.gif" alt="" /> wizards are awfully paranoid! <img src="/ubbthreads/images/graemlins/delight.gif" alt="" />
