Group test: 13 internet security suites compared

Which internet security suite is right for you?

Think all internet security suites are the same? Not even close. Our comprehensive tests show you which of today's suites to trust, and which to skip.

We tested 13 suites in all. Norton Internet Security 2010 took the top ranking, owing to its strong overall malware detection.


Kaspersky Internet Security 2010 was a close second. AVG Internet Security 9.0 placed third for its malware detection and speedy system performance.

Closely following the top picks was a competitive middle tier of suites from Avast, BitDefender, McAfee, Panda, PC Tools, Trend Micro and Webroot.

The suites from Eset, F-Secure and ZoneAlarm lagged, due to acceptable, but not great, malware protection.

For antimalware testing, we contracted the services of AV-Test.org, a respected security testing company.

We looked not only at traditional signature-based detection but also at how well the suites cleaned infections, removed rootkits, and detected malware based on behavioural analysis.

But what if the suite slows your system performance to a crawl?

This year we added a battery of tests to measure such drag: changes in boot times, application launch times, and the time to create or open a batch of documents, among other tests, both with and without the security suites running.

All the suites we reviewed had antivirus, antispyware, and antispam components, plus a firewall.

Some, such as Eset Smart Security 4 and PC Tools Internet Security 2010, had little beyond those core functions.

The rest offered extra capabilities, such as parental controls, online backup and internet browser protection.
