Unexpected behavior after rooting
Are you sure that you have malware, not just wrong settings in kinguser? (Ones that revoke and run in background using battery)

Please take look at this http://www.youtube.com/watch?v=Vl8z37PhEe0, each screen is viewed

Pause the video on each screen and match the screen up to yours (since in Chinese), taking note of settings - placement of options should be the same between languages.

Once understood and set right, follow this guide for properly rooting your device (start 8/27/2013). This guide is from the XDA developer chrono_s3rge and in English.

How to Root Motorola Razr D1 XT914:


Download the latest version of Framaroot, from XDA developer alephzain
Install and open Framaroot (you will have to enable unknown sources)
Select "BOROMIR" 
Reboot device

Check application list for SU to confirm that root worked. Update the binary, then once up and working, uninstall kingroot.

Always perform a backup, in case of issues and for data replacement.

Rooting your device is potentially dangerous, security issues arise, and other problems that could brick your device - making it unusable. Please know that you and you alone assume responsibility from rooting your device. That being said enjoy responsibly
