Try loading the phone in "Safe Mode" and see if it still shows up. If it doesn't, you are going to have to go through, when not in "Safe Mode" and find the correct app (the one that it is coming from) and uninstall that app.
To get into "Safe Mode" please do the following.
1. First turn off the phone.
2. Next press and hold "Power" until you see the manufacturers logo on the screen, then release the power button.
3. "Quickly" press "Volume Down" and hold it for few seconds until you see the message "Safe mode: ON" or something similar.
4. If you wanted disable it, simply repeat the steps above, and you should see "Safe Mode: OFF" rather than on.
