http/3 support for Kaspersky Internet Security

[xenstar]

I am using latest version of Kaspersky Internet Security
Windows 11 PRO 22H2
My browser is Brave Browser with the latest build. 
I have enabled http/3 through Adguard Home.

So under the same wifi network, on Android Mobile/Android Tablet http/3 is working. 

But on windows 11 computer, where kaspersky is installed, it's blocking the http/3 connection. (I have enabled quic support on the browser aswell)

I have checked it using http3.is website.

Please allow users to use http/3, it's faster.

So my guess was 100% correct. Kaspersky was checking all the HTTPS traffic and converting http3 to http2.

I blocked these two URLs from my network.

ksn-url-geo.kaspersky-labs.com

ksn-verdict-geo.kaspersky-labs.com

And then now my browser can use the http3.

So the issue is with Kaspersky.
