The three adware apps pose as camera-related utilities and have recorded over 700,000 installs. They hide the app’s default icon after launching the fake app for the first time and create a shortcut for launching it. When the user tries to uninstall it, they can no longer do it from the home screen, where the only option they get is to remove the shortcut. All three apps are still available in the official Android app store, but some users may still fall for them based on the promises in the description.
