Just a crappy pop up trying to get you to download something.
I would recommend to hide this (or contact a mod to remove it), because it has your ip adress in the link. Don’t worry to much about it though after you remove it, I made the same mistake before, it happens.
(If you were using a VPN, you won’t need to worry).
Also, due to websites being designed so that other people can’t access it, I would recommend to give a screenshot, and maybe a phone number or main website that it leads you to.
