A few reports coming in over the past day describe occurances where Spotify’s free streaming service on desktop computers is pushing malware-filled advertisements to users without their input.
According to a user posting on Spotify Community, the malware causes ads to launch “and keep on launching” the computer’s default browser to different sites lined with viruses (via The Next Web). Multiple macOS and Safari users have confirmed the issue to be happening on Apple systems.
Since no official fix for the problem has come from the company, many users are resorting to simply uninstalling the free Spotify player from their desktop for the time being. Further information can be found on MacRumors.
