I have not done anything to improve the compatibility of Kaspersky Internet Security with nvda screen reader
NVDA screen reader interacts with KIS graphical interface quite well
Regarding the KIS 21 program
I did an experiment: and came to the conclusion
The accessibility of Kaspersky Internet Security 2021 is less than the accessibility of Kaspersky Internet Security 20
It seems that screen readers cannot interact with the elements that make up the new graphical interface of Kaspersky: Basic, Standard, Plus, Premium
There are a lot of accessibility guidelines provided by google and microsoft
These instructions explain how a developer can improve and make their software and tools accessible with screen readers
It seems that the developers of Kaspersky: Basic, Standard, Plus, Premium did not read these instructions, at all
