Spotify forced to shut down rogue ad following user complaints about virus pop-ups

Spotify is the latest platform to fall foul to 'malvertising', after the ad-supported version of its app served a campaign that presented viewers with "questionable website pop-up" in their default browsers.
The streaming service said it has now fixed the problem, which let rogue ads automatically open virus-infected sites. 
Several users took to Twitter to complain about the issue, with one requesting direct support on Spotify's own website who called the situation "pretty alarming".&
