![]() Norton’s antispam feature adds a toolbar to Outlook and Outlook Express, and its firewall will automatically allow known, trusted applications to access the Internet. The suite did prove the fastest of the group at scheduled or manual on-demand scans that survey entire files, but it was only the sixth fastest at the more-important on-access checks that occur every time your PC opens or accesses a file. Symantec responds very quickly to new widespread malware attacks, typically in less than 2 hours, according to AV-Test.Īnother new feature, Norton Insight, uses Internet-based elements to identify trusted applications that don’t need to be scanned, which Symantec says can help improve scanning speed. But the suite’s new “pulse” update feature, which sends out malware signatures to the program every 5 to 15 minutes, could help offset that lackluster proactive performance. This put it third in the rankings, but well behind G Data, which detected a bit over 56 percent of the samples. In tests with two-week-old signature files, it identified only 44.6 percent of samples (compared to 48.2 percent in previous testing). In proactively identifying unknown malware for which it doesn’t yet have a signature, Norton scored below average. On the other hand, it was the only product that didn’t produce a single false positive by misidentifying safe software as harmful. (It was still far better than the worst performer of the batch, which detected a paltry 36 percent of adware.) In previous testing, Norton detected 96.8 percent of adware–an average showing. ![]() In dealing with adware, Norton was on the low end with its 85.6 percent detection rate for this aggravating, albeit usually harmless, software–a good bit short of the results from the top performers, which identified over 98 percent of the adware in our testing. It successfully removed nine out of nine active rootkits. It produced similarly strong numbers for detecting and removing rootkits–stealth malware used to hide infections from PC users and security software alike. It got rid of 85 percent of the files and Registry changes that malware had put in place, but it failed to scrub all the files from two out of ten test infections. Norton again took top honors in cleaning up malware infections, though it wasn’t perfect. Norton still achieved a third-place finish behind G Data Internet Security, which tagged 99.8 percent of “zoo” samples, and BitDefender’s suite, which achieved a 98.9 percent detection rate. This represents a slight decrease from our previous test results, where Norton caught 98.7 percent of “zoo” samples (98.8 percent excluding adware). In ‘s extensive malware-detection tests, Norton did very well, identifying 97.8 percent of the 722,372 collected samples of Trojan horses, worms, password-stealers, adware, and other nasties (98.3 percent excluding adware).
