Checkpoint ZoneAlarm Internet Security Suite 7.1

On the other hand, ZoneAlarm was one of only two suites that didn't entirely protect a test PC from an outside scan (Avira Premium Security Suite was the other). The firewall left a communications channel (port 135) open, and it didn't entirely hide (or stealth) the closed channels, unlike most firewalls. Checkpoint says that our results are anomalous. We suspect that the underlying reason is an incompatibility between our test PC's network adapter and the Vista version of ZoneAlarm, as AV-Test.org says that the XP version did not exhibit this problem.

As we expected, ZoneAlarm's scores in our malware detection tests were very similar to those of the Kaspersky suite. It finished third among our eight suites by catching 96 percent of dormant samples in AV-Test.org's huge 674,589-strong collection;. and it found 14 percent of unknown (to the program) malware in tests using one-month-old virus signature files. Despite using its own antispyware engine rather than Kaspersky's, ZoneAlarm's suite caught exactly the same number of spyware and adware samples as Kaspersky's suite: an above-average 90 percent.

ZoneAlarm lagged significantly behind Kaspersky on scan speed, however--at just 3.62 megabytes per second, it turned in the slowest time of any suite we tested. It also popped up the most false alerts, producing warnings about 12 harmless files. And like many suites we tested, it did a lackluster job of cleanup. The program removed only half of all files and Registry entries introduced by malware infections.

ZoneAlarm's options and interface for antivirus scanning are anemic. You can't decide whether to scan within archives for a user-started scan or for an automatic, on-access scan. You can't decide much of anything else, either. It's strange that you have many more choices for setting up the antispam engine, which ties in to Outlook and Outlook Express and is licensed from MailFrontier, than you do for the more-important antivirus scans.

In the end, ZoneAlarm's suite is good example of why you might still want to purchase a stand-alone security program instead of a hybrid suite. If you're interested in the suite's firewall, which is much more extensive than those in other suites we tested, you're probably better off buying the firewall on its own and pairing it with your choice of antivirus program.
