I was on my laptop and then suddenly a page opened and somehow I got a message and now I get messages from this page every few minutes. However, I can no longer find the page and would like to switch it off. Does anyone know how this works?
Delete all browser data. Update the virus scanner.
I don't know if I have one or how to activate it
Google the following depending on the browser used and look at pages that explain how you can deactivate this in the settings.
"Disable [YOUR BROWSER] notifications"
Which browser? Firefox: Settings → Privacy & Security → Permissions → Notifications: Click on the "Settings…" button and throw the page out.
Simply search the settings with another browser.
