AV-Comparatives Performance Test October 2021

[Gandalf_The_Grey]

Introduction
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. Taking these tests as reference, users can evaluate their anti-virus protection in terms of system speed (system performance). For further details please refer to the methodology documents as well as the information provided on our website. 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 consumer security products in these specific tests. Users are encouraged to try out the software on their own PC’s and see how it performs on their own systems.

The following activities/tests were performed under an up-to-date Windows 10 21H1 64-Bit system:
• File copying • Archiving / unarchiving
• Installing applications
• Launching applications
• Downloading files
• Browsing Websites
• PC Mark 10 Professional Testing Suite

Test Results

Summarized results
Users should weight the various subtests according to their needs. We applied a scoring system to sum up the various results. Please note that for the File Copying and Launching Applications subtests, we noted separately the results for the first run and for subsequent runs. For the AV-C score, we took the rounded mean values of first and subsequent runs for File Copying, whilst for Launching Applications we considered only the subsequent runs. “Very fast” gets 15 points, “fast” gets 10 points, “mediocre” gets 5 points and “slow” gets 0 points. This leads to the following results:

Why the impact scores of Avast and AVG are slightly different?

Based on this test, we can find that most popular AVs will not slow down your computer. Low impact on system may no longer be a selling point for an antivirus software.

I think it's remarkable so low Kaspersky has achieved to get the performance down. Now even lower than Eset. I remember around 2005, it was a heavy cousin. The blocking of malware, has always been spectacular, but today I think it has evolved to be a real great antivirus. So low impact on the computer, but still class A virus blocking. Well done Eugene.

I don't think that's really the case. While it may have been true on computers they used for testing, it won't be the case for many people. I'm sure that for most people, K7 and ESET will be lighter than Kaspersky. Kaspersky is reasonably light, but there are lighter antiviruses. My experience with using antiviruses is often quite different to the results in performance tests.

They are themselves slightly different from each other.

Kaspersky has less impact score than K7. WoOW.

I actually really like this test. Seems very accurate with many users constant feedback/experience

I trust AV-C but I always have a suspicion of Kaspersky performance test. I don't think it's that fast. It's definitely heavier than ESET
it noticeably slows down file copying speed, app launching and web browsing performance for me although not much for other people

panda deserves the top spot. It's ultralight but still it slows down significanlt the cmd, powershell or any script performance (few people use scripts)

 

[Antimalware18]

AVG!

Microsoft! Maybe there is something to it when people say it slows down their PC

please ignore my profile picture....

Based on the latest performance test, I tried to install Kaspersky's antivirus just to try it. And there IS a change compared to Webroot which is my usual antivirus. When I compare it to the model from around 2005, the difference is really incredible. Now I'm wondering if I should keep Kaspersky, or keep Webroot. Well I'll probably find a solution.
In the long run, Kaspersky would probably be the best in terms of safety. Hmm..

What I find strange in this test that the results for PC Mark and AV Comparatives own testing are so different.
Kaspersky is below Microsoft in PC Mark, but in AV Comparatives own testing Kasperski is on top, and Microsoft is at the bottom.
And if you are just browsing websites or downloading files there is no difference between all of them.
In the testing doen by AV Test there is a difference when just browsing websites...
So, while I applaud AV comparatives for the extensive testing that they do, I find it difficult to rely on their results.
The best way is still to try software on your own system...

Tbh, I find the PC Mark score more reliable. However, AV-C score carries a lot of weight in this test.
