Anti-Virus Comparative - Performance Test (Internet Security Products) – October 2014 www.av-comparatives.org

Test results
These specific test results show the impact on system performance that anti-virus products have,
compared to the other tested anti-virus products. The reported data just gives an indication and is
not necessarily applicable in all circumstances, as too many factors can play an additional part.
As we noticed that delivering percentages can easily be misinterpreted by users (as well as misused by
marketing departments or the press), and percentages would need adjustments when other hardware
specifications are being used, we grouped the percentage results by clustering them. The impact with-
in those categories does not statistically differ, also considering error measurements. The testers de-
fined the categories by consulting statistical methods like hierarchical clustering, and taking into
consideration what would be noticed from the user’s perspective, or compared to the impact of the
other security products. As the single performance results (page 9) are built using clusters, if some
products are faster/slower than others this is reflected in the results. We give the mean values (the
percentages refer to a system without a security product) of the clusters as an indication only:
