I'm receiving the same 3 ads

Hello there,
Lately I keep seeing the same 3 ads: An encrypted email service and it’s VPN, another VPN service, and a Password Manager (written in french, no less).
A few months ago I received also laptop ads and whatnot, but now it’s just these. Any idea why?
Thanks in advance.

My country is Portugal, I’m using the latest version of Brave, and Windows 10.
