I tried Mozilla FireFox, Chrome. Opera, Edge and Brave.
In none of the cases, I got a direct Kaspersky blocking in screen via WebAV / Safe Browser Module.
In FireFox and Edge, the browser directly blocked the file via its own integrated system security. I even disabled the security in FF and the file was downloaded directly to my \Downloads\ system folder, and then I got a detection via K. FileAV (UDS).
With the rest of the Chromium based browsers: Chrome, Opera and Brave, directly clicking on the [Launch The Test] link, did not start the download -> nothing happened! 🤷♂️🤔. So, to force the file downloading with these browsers, I have to right mouse click over [Launch The Test], and then select "Save Link as". This way also these Chrome and Brave browsers also blocked the downloading using its own integrated security. In Opera the file even did not finish the downloaded.
A Kaspersky WebAV / Safe Browser Module warning on screen.
