As we discussed on IRC zlib only supports the deflate compression method
which means that it can't cope with anything else.  I guess this version
of PKZIP either predates deflate or only uses it sometimes.

To reliably uncompress ZIP files I would suggest that ClamAV uses
info-zip or something (for speed perhaps only doing that if zlib barfs
on the file).  As indicated in

   http://www.gzip.org/zlib/zlib_faq.html

the zlib authors aren't terribly worried about supporting everything
PKZIP does.
