Does this website also appear for you?

When I just went online with my laptop, a strange website with the ending "-ai" appeared immediately (see photo!).

Do you know this or similar page too?

Nope I don't know this page, but it doesn't matter. Just open a new tab and close it. You may have accidentally set this page as the start page in your browser. But since you don't know her, it's unlikely.

I can't help you with the site, I don't know it. But the extension .ai indicates that the site comes from the British overseas territory of Anguilla.
