Borrowed from ZoneAlarm Pro, this one-click button shuts down all Net traffic, in and out, for those times when you want supersecurity. Among other interface enhancements and additions, we like the new Block Traffic button the best. On the NIS 2003 interface, the Status display's new green and red indicators tell you at a glance which options are active and which may need attention-very nice. For $40 (after the rebate), this firewall/virus-killer combo is the best deal in town if you don't mind the expensive technical-support fees. It has also added a bunch of other security and privacy tools, which let you, for instance, map the locale of hack attacks and stop pop-up ads. Now with intelligent intrusion detection that sniffs out suspect data transmissions (the sneaky hack popularized by Nimda and Code Red), NIS 2003 protects you from backdoor break-ins. If you're willing to spend a buck or two, however, NIS 2003 will make it worth your while. The software isn't free so, if money's tight, the no-cost version of ZoneAlarm 3.0 remains your best bet. Keeping your PC safe from hackers and virus-writing cranks is a breeze with Norton Internet Security 2003 (NIS). For details, please see our corrections page.
