Kinguser & Kingroot in Mobile Malware Removal Help & Support Posted July 20, 2016 2 minutes ago, ncrouch141 said: I found the same thing. My tablet is a RCA Viking Pro and King Root is the only way to root it and must be installed through the apk version as it wont connect to a PC. To answer bobsrighty-oh, you need a "root file explorer" like ES-File Explorer to remove King Root because it installs itself as a system app. I wouldn't worry about antivirus's saying King Root is bad because hacking tools like AutoKMS for Windows and Microsoft Office show up the same way. Just make sure you get the App or Program from its source. To add to that, People will repackage hacking tools to insert adds, actual maleware and other crap you don't want into your system, so stick with ligit sources and the developers' website of the app orprogram you're trying to get.
