The users of Spotify Free music streaming service for desktop computers have recently been reporting, on the Spotify community forum, a number of issues with the service.

According to the users’ posts, malware websites are being launched by the music streaming service on the web browsers of some users. The issue first came to light when a Spotify Free user with the handle ‘tonyonly’ said in his user report on the Spotify community forum: “If you have Spotify Free open, it will launch — and keep launching- the default internet browser on the computer to different kinds of malware/virus sites.”

About the issue, The Next Web said in a report that the vulnerability seemingly occurred on a desktop computer running Windows 10 operating system, but it has also affected other some other operating systems including macOS and Ubuntu.

Since the Spotify Free service for desktop computers typically displays banner ads at the bottom of the app window, the issue being reported with the service is apparently caused by malware-laden ads.

In acknowledging the issue with Spotify Free service for desktop computers, Spotify said in a statement released to Engadget that the problem affects “a small number of users;” and added: “We have now identified the source of the problem and have shut it down. We will continue to monitor the situation.”
