Assistant 1.0 Malicious app cannot uninstall or delete. !

Is there any other way to remove this app without preforming a factory wipe?

And

Can I still trust my SD Card?

Even Hornet Antivirus is foiled by this app. It's permissions never showed. Even before I disabled this non-manual DL, it was hidden to all but Task Manager.
Are you rooted? If you are you can remove the app in  multiple ways provided you first have:


ADB (Download standalone version to PC - )
USB Debugging enabled on phone (Settings->Applications->Development and check USB Debugging).
A PC (I will be giving windows instructions but it should carry accross the platforms) and USB cable (apparently type C works best).


Next, connect your phone to your PC and ensure the correct drivers are installed to do so (these can usually be found on your manufacturers webpage).

Launch cmd and navigate to the folder containing adb (using 'cd [filepath]').

Enter the following commands into the command line:



  adb devices 



If nothing shows here the drivers arent installed correctly or USB Debugging hasn't been enabled.



  adb shell



The interface my slightly change now, this is just accessing your phones internal commandline.



  cd system/app



Changes directory to system apps.



  ls



Find the app you want to remove on this list.



  rm example.apk



I would now reccomend rebooting when you are sure the app has been removed.

If you are not rooted try use one-click solutions so you do not have to factory reset your device such as kingroot.
