Some users report a significant performance hit using Cygwin when their
anti-virus software is enabled. Rather than disable the anti-virus
software completely, it may be possible to specify directories whose
contents are exempt from scanning. In a default installation, this
would be @samp{@code{C:\cygwin\bin}}. Obviously, this could be
exploited by a hostile non-Cygwin program, so do this at your own risk.
