Cygwin is just an application library upon Windows - there's no
isolation from Windows. If something screws with Windows, then Cygwin
can be affected too.

Cygwin isn't Linux. It just feels like Linux because many of the same
applications are provided. But it isn't Linux.

Cygwin isn't Linux, so it's not vulnerable to Linux-based viruses at
all really. Cygwin is just an application on Windows, so yes, Cygwin
is vulnerable to Windows based viruses and I'd imagine almost
completely immune to Linux-based viruses unless they are silly Perl or
shell script worms for example.
That said, a security issue affecting something like OpenSSH could
also be a problem in Cygwin. It really depends on where the root cause
of the problem is that allows the issue to arise.
In a nutshell - Cygwin is part of Windows. It's not an operating
system in its own right. It's definitely not Linux. It just happens to
do a lot of things that Linux can do because the same applications
(like perl, bash, emacs, etc) are available.
Hope this is helpful - if not, perhaps tell us what you want to achieve.
