To disable the autostart of the NCP Secure Entry Mac Client GUI application on a Mac, just edit the /Library/LaunchAgents/com.ncp-e.ncpmon.plist file and set the value "RunAtLoad" to "false" (from "true"). It's faster to do it via command-line, like this:

$ sudo nano /Library/LaunchAgents/com.ncp-e.ncpmon.plist

Then move the cursor right below the line containing "RunAtLoad" and change true to false.

Cmd+X, Y, Enter

Ready!
