Patrick,
   That's not the point, or at least my point. I don't want to reject
ALL zip files. I only want to reject zip files that have a virus
embedded in them. Please remember the problem I'm trying to address.
Someone sends me a virus infected file inside a zip, which is what has
been happening for the last few days. Zip files have value. I should
accept zip, and even zip with an exe in it, as long as they are not
infected. That requires virus protection TTBOMK.

Thanks,
Mark
