![]() We copied a set of various common file types from one physical hard disk to another physical hard disk. 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 6). Some anti-virus products ignore some types of files by design/default (e.g. As we find this misleading, we still do not publish boot times in our reports.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 some time 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 how they impact on their systems (due to e.g. We also used a third-party, industry-recognized performance testing suite (PC Mark 8 Professional) to measure the system impact during real-world product usage. We simulated various file operations that a computer user would execute: copying different types of clean files from one place to another (we use around 3GB of data consisting of various file types and sizes (pictures, movies, audio files, various MS Office documents, PDF files, applications/executables, Windows operating system files, archives, etc.)), archiving and unarchiving files, encoding and transcoding (converting MP3 files to WAV, MP3 to WMA and AVI to MP4) audio and video files, converting DVD files to iPod format, downloading files from the Internet, launching applications, etc. After each run, the workstation was defragmented and rebooted. 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 hard disks were defragmented before starting the various tests, and care was taken to minimize other factors that could influence the measurements and/or comparability of the systems. The tests were done with an active Internet connection to allow for the real-world impact of cloud services/features. The performance tests were done on a clean and fully updated Windows 8.1 64-Bit system (English) and then with the installed Internet security software (with default settings). The tests were performed on an Acer Aspire XC600 machine with an Intel Core i5-3330 CPU (3GHz), 4GB of RAM and SATA II hard disks. ![]() The following activities/tests were performed under an up-to-date Windows 8.1 64-Bit system: Also, keep in mind that different vendors offer different (and differing quantities of) features in their products. Please note that the results in this report apply only to the products/versions listed above (e.g. Trend Micro Titanium Internet Security 8.0 Additionally, Microsoft Windows Defender integrated in Windows 8.1 has also been evaluated. ![]() The following products were evaluated (with default settings) in this test. We used the latest product versions available at time of testing (October 2014). Users are encouraged to try out the software on their own PC’s and see how it performs on their own systems. We want to make clear that the results in this report are intended only to give an indication of the impact on system performance (mainly by the real-time/on-access components) of the security products in these specific tests. ![]() Taking these tests as reference, users can evaluate their anti-virus protection in terms of system speed (system performance).įor further details please refer to the methodology documents as well as the information provided on our website. The Performance Test evaluates the impact of anti-virus software on system performance, as programs running in background – such as real time protection antivirus software – use some percentage of system resources.
