Test System And Benchmarks

Do Virus Scanners Slow Down Your System?
By

We begin by selecting the security software to test. We're curious to find out if Internet security suites might contain bloatware that could slow down a system more than a simple anti-virus program would, so we've included not only virus scanners, but also complete Internet security suites offered by noteworthy developers. This means we’re testing AVG Anti-Virus, AVG Internet Security, Kaspersky Anti-Virus, Kaspersky Internet Security, McAfee VirusScan Plus, McAfee Internet Security, Norton AntiVirus, Norton Internet Security, Trend Micro Titanium AntiVirus+, and Trend Micro Titanium Internet Security. [edit: we originally listed some obsolete versions of the AV software. The programs we actually tested were the newest available versions as of October, 2010]

Where benchmarks are concerned, we’ve assembled a suite of tests to exercise most aspects of PC performance, from gaming to office work. We’re testing raw application performance and also the time it takes for the system to respond to boot and to program launch requests. In order to do this, we’ve even developed some custom benchmarks, courtesy of our own Andrew Ku.

While we're running the benchmarks on an Athlon II X4 645, we'll be disabling two of the CPU cores for the majority of benchmarks. As a result, most of the benchmarks reflect the performance users can expect from a budget dual-core CPU. On page seven we run more benchmarks with only a single CPU core enabled, and also with all four CPU cores enabled, to see if the performance burden changes based on the number of execution cores available to the system.

With all this in mind, here are the particulars for our test system and benchmarks:
