Hi, I had constant infuriating popups on the login screen of my Samsung S4. Installing and running Malwarebytes Anti-Malware Mobile detected three malware apps: Android/Trojan.Clicker.m /system/priv-app/AlarmeController.apk Android/Trojan.Downloader.CalServ.dy /system/priv-app/CalendarService.apk Android/Trojan.Dropper.Gorpo.b /data/app/com.android.system.app.native8-1.apk The last of these did uninstall when I hit Delete. The first two say: "Uninstall unsuccessful", and I can confirm that I am still suffering constant popups. I have been through a bunch of other things such as turning off popups in the browser, blocking data usage to those apps etc with no effect. Any suggestions would be gratefully received. Thanks
