Spotify ads 'launched virus pop-ups'

The so-called malvertising affected Spotify's subscription-free service on Windows, Mac and Linux machines.

People reported that virus-infected pop-up websites were appearing while they listened to music.

Spotify said in a statement: "We have now identified the source of the problem and have shut it down."

It said "questionable website pop-ups" had affected a "small number of users".
