Hi Tommy,
You can try using this troubleshooter to repair registry issues that might be blocking you from removing Reason Core Security.
If, however, you're still unable to uninstall the app, we suggest contacting the respective support team for instructions on uninstalling it.
Uninstalling security software is a somewhat of a common thing. The reason behind this is to deter malware from actually uninstalling it. Needless to say, there's always a way to accomplish it.
Let us know if you need more help.
