In addition, it does not show any icon and is activated by taking advantage of daily expedients such as connecting the cable to power the battery, restarting the system or installing an app. He had heard of xHelper in February and immediately appeared as a rather threatening danger as apparently "immortal".

An extreme method is the complete re-installation of the operating system, but the prerogative of expert users. A more viable solution is that suggested by cyber security experts from Malwarebytes. Here is the procedure:
– a file manager must be installed by downloading it from Google Play;
– you install an antimalware like Malwarebytes for Android;
– disable Google Play by bypassing the re-installation of the malware by going to Settings> App> Google Play Store> Disable;
– the system is scanned with antimalware;
– open the file manager and search for files that start with "com.mufc" and are deleted (but you must not touch the Downloads folder);
– now from Settings> Apps> Google Play Store> Activate;
– restart the system.
