Charter - Spectrum - NDSPCShowServer
I had this same issue but with the Charter cable version. Seems they are the same.
The removal process was the same
user > Library > Internet Plugins > PlayerPlugin.bundle
user > Library > LaunchAgents > com.nds.pcshow.plist
user > Library > LaunchAgents > com.nds.pcshow.uninstall.plist
user > Library > NDSPCShowServer > NDSPCShowServer.bundle
user > Library > NDSPCShowServer > uninstall.command
except that after deleting these files and then killing NDSPCShowServer in Activity Monitor it would simply relaunch. In sampling the process I found it coming from a hidden folder //Users/Library/.nds
To see it in Finder do GO --> Go to folder .nds
After deleting that folder the process would stay dead after killing it.
