Virus scan of all proxy requests

Hi,
Just wondering if anyone knows of a utility to scan all exe, com, zip
whatever files for viruses as they pass through the squid proxy? I am
working for a large organisation that needs this, as many users download
viruses and dont scan for them, have scanning on all incomming email
working, and this has stopped 60% of viruses but the other 40 is comming
in from the proxy. was looking at writing it myself, using redir, but am
having some dificulty... any ideas?
