The point is 90% of our users don't need zip support and
now they can open any of these new zip file viruses that
may get past the gateway virus scanner. The link that
you reference only says to run regsvr32 /u zipfldr.dll
which I mentioned in my post. This doesn't work. The
next time our double-click on a zip file, zipfldr.dll re-
registers itself and opens up the zip file.
