Following close behind are the security packages from Bitdefender and Qihoo 360 with 5.3 and 5.7 points respectively. As previously mentioned, the maximum perfect score was 5.0. The lowest influence and thus the best speed-performance rating was achieved by the product from Kaspersky with only 5.1 load points.
All partial results of the tests were aggregated and at the end divided by the number of 7 test rounds. Thus for all 5 test sections, this resulted in a perfect score of 5 and a worst score of 25 load points. For 21 to 40 percent there were 2 points, for 41 to 60 percent drop in performance, 3 points, and so on up to 5 points. If an antivirus application slowed down a system between 0 and 20 percent, it received 1 load point. A more in-depth explanation on the topic of reference systems can be found later in the "Test Configuration" section.įor all products in the tests, it was measured how long they required for various test sets, in order toįor all subsections, load points of 1 to 5 were assigned after each test, whereby a score of 1 represents good and a score of 5 poor. The reference system without any protection software was used for later comparison of the measured performance ratings. In addition, a Windows system with the freeware Microsoft Security Essentials or Defender (for Windows 8/8.1) was put through all the tests as an additional comparative figure. Included in the test were products from Ahnlab, Avast, AVG (freeware and purchase product), Avira, Bitdefender, BullGuard, Comodo, ESET, F-Secure, G Data, Kaspersky, McAfee, Microworld, Norman, Norton, Panda, Qihoo 360, Quick Heal, Tencent, Threat Track and Trend Micro.
