Cygwin ( www.cygwin.com ) is a very powerful Unix-like system on top of windows, we use it in addition to native Linux and Mac OS systems.
One of Cygwin options is to start a command shell, which opens a window where you can interact by means of commands.
Today, after a McAfee update, the comand shell prompt seems to be blocked by McAfee.
If we turn-off McAfee for the usual 15 minutes, the command shell prompt appears again.
Should we configure McAfee differently ?, are we missing something ?, please let us know.
