“McAfee may not be installed” during Cgywin installation

Hi all, I'm new to the Intel FPGA board and currently trying to follow the user guide for DE1-SoC.

To use SoC EDS, I have followed the installation guide for Windows in https://rocketboards.org/foswiki/Documentation/SoCEDS

when I’m installing Cygwin as the instruction in https://rocketboards.org/foswiki/Documentation/SoCEDS#Install_Cygwin , I have this McAfee may not be installed problem:

Does anyone know how to overcome this issue?
