I was playing music (playlist) and twice this morning it changed to something else entirely while stopping to output on my speakers. I checked and it says that it is outputting on something called Spybot. It also showed a graphic that suggested that it was a speaker. I do not have such a speaker on my network. The wifi is coming through the Eero system. I told Spotify to forget the spybot speaker, but it came back automatically. What should I do to get rid of this nuisance?
