It doesn't bother me in the slightest, I live in the real world.
I also take additional precautions, if you don't back it up are you prepared lose it. I do regular system and data backup, in the unlikely event I have a problem, be that system or data attack. I have been using Avast Free for over 17 years and no issues, but I always plan for the worst and hope for the best.
I'm also confused as the the value of this 'old' test, whilst the article is dated 'March 09, 2022' the test appears to have been run in November.
In the current November test, the products subjected to 10 attacks could achieve a possible 36 points for a maximum protection score. Those achieving lower scores experienced problems in one or more scenarios.
Conclusion, should these test results have been sent to the respective Companies, in much the same way as VirusTotal does for undetected samples. Are they now covered by those Companies that didn't prevent the attack over 4 months later ?
This seems to be your personal hobby horse (not mine), if you don't like the results there is nothing stopping you choosing another AV solution.
