Some virus protection software companies have flagged the UCCNC installer as possibly containing a "trojan virus". Rest assured, there is absolutly ZERO threat of a virus contained within the UCCNC installer. We are working diligently with the creators of UCCNC and companies such as Norton to have this flag removed so our customers can have a smooth installation process. For now, you may need to turn your virus protection off to install the UCCNC.exe file. You can immediately turn the software back on as soon as the program has been installed. We apologize for the inconvenience! If you have any questions or concerns, please feel free to give us a call directly at (203)556-1856.
