Some very strange ads keep popping up on my MAC chrome screen. They are all the same type, with a big black round X symbol to close them, but sometimes they block the page content. I cant find a solution because I don´t know how they're called. they aren't really pop ups, because they show up on the same screen as the page content, not on a diferent tab or window, but it does prevent me from using the explorer, especially when I'm on cuevana or some oher live stream page.
Thank you all for your help.
