I just saw this and thought that maybe Symantec might be interested in this information about Zone Alarm Pro's latest version that was just released on Aug 31
"To serve our customers who have a need for a streamlined high-end firewall product, especially to complement an existing anti-virus program, ZoneAlarm Pro firewall no longer includes the anti-spyware feature. To further streamline in an age where web privacy controls are built into the most popular browsers and email attachment scanning is included in the major email applications, privacy controls and inbound MailSafe have also been removed with this release.
