Everything evolves
Microsoft have made great efforts since the addition of AI Machine Learning, even I am still shocked!
I remember in the past that Microsoft's solutions were bad... (Microsoft Security Essentials on Windows 7 / Windows Defender on Windows 8)
Just this little interface bug that remains annoying when I scan a pack (but since Mrs Michu doesn't get infected by 700 000 malwares per day, I didn't underline it too much)
It seems that MD and Avast are closer in 2021 to the top AVs (in the Consumer Real-World scenario) compared to the period 2019-2020.
REAL-WORLD 2021 (Triathlon = AV-Comparatives + AV-Test + SE Labs)
12 tests
Avast, Microsoft, Kaspersky, Norton ....... 10.5 missed samples
Result rescaled because in the year 2021 there were slightly fewer samples.
Real-World 2019-2020 (Triathlon = AV-Comparatives + AV-Test + SE Labs)
24 tests
--------------------------------- average per 1 year
Norton 360................ 4 missed samples
Kaspersky.................. 9.5 missed samples
Avast, Microsoft...... 18.5 missed samples
