ZoneAlarm includes a two-way firewall, antivirus protection and an optional security toolbar that warns you about dangerous websites.
In the latest version, the user interface has been revised once again and no longer confuses the user with licence warnings, which only relate to the paid version. Now you can see at a glance whether the firewall or the virus scanner are functioning properly.
