problem solved @Igor Kurzin , to enable the install, i had not just to "pause" KAspersky security, but to close it completely !

Hi everyone, Something strange happened to me yesterday and today: Yesterday, once I logged into my home banking site, the screen suddenly went black, even the mouse pointer was invisible, and after a few seconds everything returned to normal and the site was visible again. Today, the same thing happened while I was watching a music video on YouTube. As for home banking, I didn't use Safe Money, but in general, I installed the Chrome extension and set it to block data collection and banners. Thank you all.

Merci pour votre réponse. Je vais attendre les prochains jours/semaines pour obtenir la mise à jour qui résoudra probablement le problème. Bon week-end :))

Würde vorschlagen ein Ticket beim Support zu eröffnen.

I understand that these are currently only my hypotheses, so I am seeking confirmation and assessment from the community. Furthermore, I have taken the step of submitting a request to Kaspersky Technical Support regarding this issue.

On what basis do you draw this conclusion? None of the above suggests this.

I have been doing that for a while. For most accounts involving personal security, I use two-factor authentication (2FA) and unique, random passwords (which I store in the Enpass application). However, the hacker exploited this by utilizing an App Password for access, which bypasses 2FA. Furthermore, the Enpass application itself is installed on this very device.

If you suspect a brute force login cancel email and switch to an Authenticator app or sms ?
