Our test system was a Compaq Evo W4000, running Windows XP Professional, with an Intel P4 2.4GHz processor and 512MB DDR RAM. With EZ Antivirus 2005 running, our test system scored a remarkable 100--with no reduction in overall system speed. By comparison, McAfee scored a 97, or a 3 percent decrease; Norton AntiVirus 2003 scored a 95, a 5 percent reduction. (An Internet-content-creation score of 100 represents the performance of our test system without any extraneous software running.) In a test of scanning speed, EZ Antivirus 2005 took an average of 2.6 minutes to scan a 1.3GB directory, but that couldn't match speed-demon PC-cillin, which averaged 2.4 minutes.

To determine whether EZ Antivirus effectively blocks viruses, we gauged its performance in tests conducted by independent antivirus laboratories. In Virus Bulletin's tests with live viruses, EZ Antivirus earned the coveted VB 100 percent rating 70 percent of the time in the last 10 Windows tests--a good showing, certainly, but not on a par with Norton AntiVirus, which earned the title on 10 of its last 10 tests.
For more details on how we test antivirus apps, see CNET Labs site.Like its competitors, Computer Associates provides free e-mail support for its EZ Antivirus 2005 product, but it charges for phone help. In our tests, e-mail queries were answered relatively quickly--typically within 3 hours in an industry where a 24-hour turnaround is standard. The replies were polite and helpful, too. For instance, our problem with the flashing EZ Antivirus icon (in the taskbar tray) was attributed to a temporary problem with the vendor's AutoDownload server. (The problem eventually resolved itself.) Online help is good, too. The Ask Sammy query box lets you type in natural-language questions, such as "What's the Bagle virus?," and get a quick list of knowledge-base documents on a given topic.
Phone support, however, is expensive: $49.95 for one tech issue, $99.95 for three issues, and $149.95 for five. Then again, these rates are comparable to those of Computer Associates' leading antivirus contenders, including McAfee, Symantec, and ZoneAlarm. Trend Micro, which provides a year of free phone support, is the lone exception here.
