cleaning uploads

[jekillen]

Hello again:
Does anyone on this list know of a system or software bundle
that can be used with php to clean uploaded files. Specifically,
embedded php or shell scripts, shell escape chars, viruses,
executable code in image files, anything that might be hazardous
in any file that might be capable of being sent as an e-mail attachment?
Using FreeBSD 6.2, Apache 1.3.37,  php 5.2.1, web site to receive
uploads will be using ssl.
I have asked on the php general question list but have not gotten
a useable response.
Thanks in advance;
Jeff K
