Laptop help chat free

Hello,
I would like to ask a question about my laptop's network.
When I'am at my own place the internet works fine either wireless or wired, no problems there. no Commercials when wanting to watch a movie.

But as soon as I get to my mothers place, my laptop goes crazy. The vent is suddenly going crazy. He keeps prosessing things and internet commercials keep popping up. It's weird cause about a month and a half ago he didnt do this.
