To be clearer, the screen appears to me too, but only after waiting for the Avast icon to appear / be loaded in the application bar.
However, the Defender icon appears much earlier and if in the meantime, I was also saying 50-60 seconds, I click on it and the screen with Defender activated appears. After those seconds, the screen changes and Avast is activated. I think I was clear and in any case, regardless, I hope that some users, better than me, want to report the loading times of Avast which seem to me to be excessively long. This can be justified only when, when the PC starts, it downloads the virus definitions updates but this Avast does not do it right and only every time the PC is started!
