Android users around the world have been alerted about 38 apps formerly on the Google Play store that came with a malicious hidden feature.
As mobile gaming apps makers tapped into the popularity of Minecraft with the copycat games, online security experts have warned several of these popular games contained hidden advertising.
McAfee's Mobile Research Team discovered 38 of these dodgy apps on the Play Store had been downloaded 38 million times. The experts say the apps "stealthily" loaded adware in the background of mobile phones as users play the game none the wiser.
