I think it's pretty important to try understand that the quoted test included stable version 17.8. F-Secure is not really a company known for releasing " stable " versions that nuke/destroy peoples machines/systems. Today, the latest stable version is 17.9 and considering that version includes several " performance improvements ", next test should probably be the same or maybe even better, but that we will know for sure when that test is shared/posted.
In general from what I know and what I seen over many many years, F-Secure has very few genuine performance issues if any. F-Secures issues lays elsewhere and for those that follow the development progress, know or recall that when version 17.8 was released, it had followed a beta test that lasted over 1 year. That could very well been one reason why F-Secure got a good performance result. But it got a less good result in another test where the previous history of a bit too much false positives made it's return. It clearly shows what F-Secure needs to work on and improve.
A small advice for those people that seems to go ballistic/rant like nuts over AV tests. Please calm down and go outside for a bit of fresh air! These tests comes with disclaimers. Read those! The results is Not and never will be the end of the world.
Kaspersky had a certificate issue warning because of it scanning https,but I have not had the problem since...Maybe others can chime in,
Probably better talked about in the Kaspersky section or the actual AV-Comparatives thread.
AV-Comparatives released their latest Performance Test Report for consumer security products under Microsoft Windows 10. Performance Test October 2020 - AV-Comparatives 17 consumer products were tested regarding their impact on system performance. But keep in mind: Protection is more important...
