Computer security software - performance matters

There are many ways to measure performance of your computer security software. Below are the test results of three key measurements - download size, install time and overall performance.

Symantec Corporation, the parent company for products like Norton Internet Security, hired a third party, PassMark to run performance tests for its security products and their major competitors.

Here are the results as released by Symantec. "Only two Internet Security products had high enough performance across the six test metrics to average 5 stars, ZoneAlarm IS 7.1 and Norton IS 2008." The details of these test results are available online here.
