So did I; and I've checked to make certain it doesn't. Mind you, I don't think or claim that ZoneAlarm is perfect. I used to be perfectly happy with an even better app called AtGuard - first shareware I ever registered when I started on the net. Never a problem. Until they sold out to Symantec, who (supposedly) upgraded it as Norton's Internet Security. I liked Norton Utilities, so I "upgraded" eagerly. Quite disappointed to find that Symantec had decided that removing nearly all user-controls & customisable options was an improvement. That and a whimsical tendancy to turn itself off randomly without notifying me, requiring a complete re-install before it would work again - only to quietly de-activate itself a couple of days later. Couldn't re-install AtGuard, as I'd lost my registration number by then. ZoneAlarm came very highly recommended. Does 80% of what I want a firewall to do. Happy with it (for now :-))
