Trend Micro Internet Security Pro's broad feature set combined with its look and feel make it a serious contender, but its questionable efficacy and middling performance make it a program we're not recommending.
Most people won't need the extra security tools in MIS. You're better off buying the standalone VirusScan 6.0 or Norton Internet Security and downloading a free firewall such as ZoneAlarm.
Going by older detection and removal numbers, Trend Micro AntiVirus plus AntiSpyware offers competent if basic security protection. However, so do many free competitors. This year, we recommend giving Trend Micro AntiVirus plus AntiSpyware 2010 a pass.
Kaspersky Anti-Virus 2010 offers pricey antivirus protection. The 2009 version scored well on independent antivirus detection and removal tests, but be prepared to pay a premium for what you're getting.
While Symantec's protection is solid, the overall user experience within Norton Internet Security 2008 could be much, much better. Not all the features work together, and the program could use fewer system resources. We can also do without the addition of paid services within the technical support section.
Panda Antivirus 2008 is slower than the competition and lacks independent, third-party antivirus test results, and thus doesn't receive our recommendation.
McAfee VirusScan Plus 2008's protection keeps up with the changing threats on the Internet, but the product itself doesn't excel.
McAfee Total Protection feels like a grab bag of security and performance tools without any clear focus, which will likely frustrate the average user.
Norton Internet Security 2007 makes significant gains over last year, including cutting-edge rootkit and behavioral monitoring features found nowhere else, but the overall package could be serious overkill for the average desktop owner.
With VirusScan 2006, McAfee greatly enhances user protection against spyware and adware threats but slows your system down in the process.
