"Auto-rooting adware is a worrying development in the Android ecosystem in which malware roots the device automatically after the user installs it, embeds itself as a system application, and becomes nearly impossible to remove. Adware, which has traditionally been used to aggressively push ads, is now becoming trojanized and sophisticated. This is a new trend for adware and an alarming one at that.
Lookout has detected over 20,000 samples of this type of trojanized adware masquerading as legitimate top applications, including Candy Crush, Facebook, GoogleNow, NYTimes, Okta, Snapchat, Twitter, WhatsApp, and many others."Additionally:
"To add insult to injury, victims will likely not be able to uninstall the malware, leaving them with the options of either seeking out professional help to remove it, or simply purchasing a new device."
