Google has removed 85 fake adware apps from its Play Store after finding out that they were pushing aggressive, full-screen adware to Android users. Adware has traditionally been used to aggressively push ads like banners or pop-ups on mobile screens to make money for its makers. The apps can display ads even when you are not browsing the internet, hide themselves and run in the background on infected devices. The most popular fake app in the list was Easy Universal TV Remote, which was downloaded more than 5 million times before it was removed.
