This is the detection for a potentially unwanted modification (PUM) on the registry that prevents the user from accessing the command prompt in Windows. This is often done by malware to hinder the user in removing it. The user gets the error message, “The command prompt has been disabled by your administrator”, when he/she tries to open the command prompt.
