CNET editors' review

Reviewed by: CNET Staff

Along with its effective and easy-to-use firewall and additional security features, this new version of ZoneAlarm Pro brings mostly solid antispyware protection to the table. ZoneAlarm Pro makes configuring a firewall, which sounds like a daunting task for the majority of computer users, incredibly easy with the included wizard. Maintaining and updating settings also is a snap when you're using the application's stylish interface and its simple slider controls. The app now boasts an ultrasecure triple-layer firewall, which safeguards your machine's OS and Registry. Experts will appreciate options that let them set up custom rules. The program's Zones feature also allows you to assign different security levels for a local network and the Internet. We found ZoneAlarm Pro very good at recognizing and automatically including settings for our local network. In all our tests, the firewall guarded against all external and internal threats it encountered.

ZoneAlarm Pro includes a cookie cleaner, an ad blocker, a pop-up stopper, and new antispyware tools. Happily, the app offers both real-time protection against malware as well as a scanning engine. In our tests, spyware scans were blisteringly fast and almost always accurate, though ZoneAlarm Pro did leave a few minor traces that some dedicated utilities removed. The real-time module also fared pretty well, but we wish it offered more information on potential threats from directly within the program. Elsewhere, we like the configuration options for the privacy-protection features, which let you individually apply settings to different Web sites. The ID Lock feature, which lets users specify what information the firewall should prevent from being sent out via the Web or e-mail, also is a nice touch. With a tougher firewall and the addition of antispyware tools, this excellent program just keeps improving.

Publisher's description

ZoneAlarm Pro automatically blocks known and unknown Internet threats for home users, small-business owners, and corporate employees working remotely. The program monitors outgoing application traffic, as well as incoming traffic to protect you from any local applications attempting to use your Internet connection to communicate with the outside world. You have the option to grant or deny access on a per-application basis, customizing the protection of your system. ZoneAlarm Pro also offers password protection, automatic mobile-PC protection, and e-mail-attachment protection for 47 file types. ZoneAlarm Pro features online-privacy protection with pop-up stopping, ad blocking, and cookie-control features. The latest update adds Complete Mailsafe for blocking suspect e-mail, Cache Cleaner for eliminating traces of your Internet activity, expert firewall controls, and Hacker ID for tracking and mapping hacker attacks.
