I bought a THL T9 Plus recently and get some preintalled apps on it, like YouTube. I thought, that this apps are original, because Google Play client recognised these too. My phone behaved strange in some cases, so I tested it with Malwarebytes Anti-Malware. It found: Android/Trojan.Spy.Agent.YQ in system/priv-app/thl_YouTube folder.

  • You cannot remove that malware without rooting the device, but you can disable it though. You can do that via Settings -> Apps.

  • @Firelord: I already tried it, but after restart I got an error message, that this application stopped. I press OK and popup window comes back again and again. So I decided to allow it again.

  • Hmm....I wonder whether you could delete this by using a terminal emulator...

  • You could hide them via adb, what should work. But as far as I know just at and over nougat. Here is the video link to how you could do it. It's from xda

To remove or freeze pre-order installed apps you need to root your device - without rooting you cannot uninstall system apps (those that came bundled with the OS )

    Custom ROM is problematic, because some applications need original ROM.
