The independent organization AV-Comparatives tested the most popular anti-viruses on Windows 10 to determine which one has the least negative impact on computer performance.
A good antivirus, regardless of whether it is paid or free, should first of all provide the greatest protection. Numerous tests have shown, however, that among these most popular programs the differences are really small, so when choosing the best solution for yourself you can also be guided by other features. One of the key may be how strongly individual applications affect the performance of the computer they protect. Check it has been decided by the independent organization AV-Comparatives.
The organization tested 16 programs designed to protect computers with (64-bit) Windows 10. In addition to the integrated Windows Defender solution, 15 applications were selected that are very popular – both typical anti-viruses and Internet Security packages. They were all installed on the same machine (with a sixth generation Intel Core i3 processor and 4 GB of RAM on board).
What was the test about? To measure the negative impact of background programs on computer performance when performing various operations. The latter include copying and archiving files, browsing the Internet and downloading files from the network, as well as installing, running and uninstalling applications. In addition, the PC Mark 10 Professional Testing Suite benchmark was also used.
What are the results? It turned out to be the worst … Windows Defender. Its negative impact on performance was rated at 27.3. Even the programs occupying the next two places by Avira and Trend Micro are doing much better (they achieved results of 16.1 and 13.7 respectively). As for the leaders of the ranking, four programs deserve a special mention, the indicators of which did not exceed the point: these are the applications of McAfee, VIPRE, K7 and – above all – ESET.
