The results already consider the fingerprinting/optimization technologies of the anti-virus products, as most users usually make archives of files they have on their disk. We archived a set of different file types that are commonly found on home and office workstations.

We copied a set of various common file types from one physical hard disk to another physical hard disk.Īrchiving and unarchiving:Archives are commonly used for file storage, and the impact of anti-virus software on the time taken to create new archives or to unarchive files from existing archives may be of interest for most users.
based on their file extensions), or use fingerprinting technologies, which may skip already scanned files in order to increase the speed (see comments on page 5).

We use around 4GB of data consisting of various file types and sizes (pictures, movies, audio files, MS Officedocuments, PDF documents, applications/executables, Windows operating system files, archives, etc.).įile copying: Some anti-virus products ignore some types of files by design/default (e.g. As we find this misleading, we still do not publish boot times in our reports. Users may notice that sometime after the system has loaded, it will become very slow for a little while thus, it initially looks as though the system has loaded very quickly, but in fact the security product just loads its services belatedly, leaving the system more vulnerable. Some security products load their services very late at boot (or even minutes later). It is also important to consider when the protection provided by the security solution being tested is fully active, as this could be a useful measure of boot completion as far as the security solution is concerned. The most significant issue is to define exactly when the system is fully started, as many operating environments may continue to perform start-up activities for some time after the system appears responsive to the user. Measuring boot times accurately is challenging. Security products need to load on systems at an early stage to provide security from the very beginning – this load has some impact on the time needed for a system to start up. software conflicts and/or user preferences, as well as different system configurations that may lead to varying results). Readers are invited to evaluate the various products themselves, to see what impact they have on their systems (due to e.g. We used the predefined PCMark 10 Extendedtest. We also used a third-party, industry-recognized performance testing suite (PC Mark 10 Professional) to measure the system impact during real-world product usage. We perform each test multiple times and provide the median as result. This is especially true for performance testing, as some noise is always present on real machines. We believe that increasing the number of iterations increases our statistical precision. We simulated various file operations that a computer user would execute: copying* different types of clean files from one place to another, archiving and unarchiving files, downloading files from the Internet and launching applications (opening documents). After each run, the workstation was reverted to the previously created system image and rebooted six times. The tests were repeated several times (with and without fingerprinting) in order to get mean values and filter out measurement errors. 
Optimizing processes/fingerprinting used by the products were also considered – this means that the results represent the impact on a system which has already been operated by the user for a while. The tests were done with an active Internet connection to allow for the real-world impact of cloud services/features.Ĭare was taken to minimize other factors that could influence the measurements and/or comparability of the systems.

The performance tests were done on a clean Windows 10 RS3 64-Bit system (English) and then with the installed consumer security software (with default settings). We consider this machine configuration as “ low-end”. The tests were performed on a Lenovo G50 machine with an Intel Core i3-4005U CPU, 4GB of RAM and HDD hard disks. The following activities/tests were performed under an up-to-date Windows 10 RS3 64-Bit system: Also, keep in mind that different vendors offer different (and differing numbers of) features in their products. to the exact version numbers and to 64-bit systems). Please note that the results in this report apply only to the specific product versions listed above (i.e. We have tested the product that each manufacturer submits for the protection tests in the Consumer Main Test Series. This test includes both “Antivirus” and “Internet Security” consumer products – both referred to as security products.
