Good night @Flood and Flood's wife.
I'm sorry, but I think I didn't express myself correctly.
As for Opera and Vivaldi, I already believed in you the first time. That's why I skipped topic 1 in my last post. I was just surprised that these browsers aren't supported, as Kaspersky seems to be working normally. For example, I'm attaching a screenshot of Protected Browser working in Opera.
But I understand that maybe Kaspersky developers don't guarantee that everything will always work 100% in these browsers, which is why they say these browsers aren't supported. I'm just surprised to learn that it works so well in browsers where it shouldn't. That's all.
However, even though these two browsers aren't supported, I also did the test in four other browsers that are supported. So this is kind of irrelevant, because the problem is happening in all browsers. The print I sent you previously, for example, was in Chrome. This is what was on my mind when I replied to the second topic. I was no longer thinking about Opera or Vivaldi.
You sent me a list of the browsers supported by CTV, and their respective versions. I had already said that I also tested it in Chrome, Edge, and Firefox, so I just added the information that they are all up to date.
By the way... CTV was just an example. This issue occurs on absolutely every video streaming website I've visited, with the exception of Disney+, Netflix, and Prime Video.
And last, but not least, my joke when answering topic four, is that, as I said in topics two and three, the problem disappears when I turn off the antivirus. The problem isn't the browser chosen, the version installed, the website accessed, the existence of DRM, or whatever. The problem is that while Kaspersky is activated, online video playback is hampered.
Maybe the problem is caused by some Kaspersky update failure, or maybe it's a conflict with something else I have installed on my computer. But for sure the problem is related to Kaspersky, or it wouldn't go away when the antivirus is turned off.
I hope that now I have expressed myself better, and properly explained my answers.
I've already contacted support, and I'm waiting for a response. Having an answer, I'll come back here to update.
Thanks.
