sh.exe hangs, but I can kind of get things working if I don't disable McAffee

If I don't disable Privacy Service:

If I run /usr/X11R6/bin/startxwin.sh (from bash without calling sh), the
script gets to
===============================================================

===============================================================


If I press Enter at this point, I get a command prompt.
ps indicates that I have bash, xterm, XWin, and sh (child of XWin) running.
I don't see an xterm.

I try to run xdvi.  It shows up in the process list, but I don't see an
xdvi window.
In order to get xdvi running, I first have to type in
export DISPLAY=127.0.0.1:0.0

If I open another cygwin prompt and kill -9 /usr/bin/sh from it, XWin spits 
out:

===============================================================

At this point, xdvi pops up (but is non-functional).  A completely 
functional
xterm pops up.  If I set the DISPLAY properly on both cygwin windows, I can 
call
gv, xfig, xeyes, xpdf, xterm, xemacs, etc--they all work, although xdvi is 
still
unhappy and vanishes the moment the cursor is over it.
Etc, etc.  So, everything that I've tried except xdvi is fine, except when I 
try
to exit from cygwin.  I have to kill -9 XWin.

On the other hand, if I disable McAffee Privacy Service before starting
cygwin, on calling starwin.sh, I get

===============================================================

This time, though, killing sh  kills its parent XWin.  Exiting from cygwin 
is
not a problem.
Why does XWin.exe spawn sh.exe?  What is it doing?  How is it interacting 
with
the firewall?
Well, I guess I'm hoping mostly that someone can fix things.
