At least on the Verizon Moto G, I believe this is now "MotorolaOTA", package name com.motorola.ccc.ota. You can disable the package via root ("freeze" it) rather than renaming it (even with root methods that disallow writing to /system).
The APK is located at /system/priv-app/3c_ota.apk. If you're using FX with the root module (free one works) go to that file, long-press on it, tap "Details", scroll down a bit and tap "Disable Package".
