I've been playing with Squid for a few months, and have even talked a few people into converting old machines into squid servers for their home networks. All in all, I don't even know what its like not to have one running.

Anyway, I'm at that next step, where I'm not happy enough.. I want more.

I'm looking for a way to have a website that passes through Squid to get a quick virus scan from ClamAV before the site is served to the end client.

Ultimately, I'd like to set up a Squid/Xmail server to make my home browsing and mailing as safe as possible without having the end-user install virus scanners, and spyware blockers as most of these end up giving you spyware and/or virus'.

Don't know about using ClamAV directly in conjunction as an external helper within Squid, but if you implement DansGuardian alongside Squid which also provides additional content filtering (which you can disable if you don't need it), there's a plugin which uses the ClamAV engine quite nicely.

i've got a how-to writtern on my website about something like this, it's using havp (http anti-virus proxy) check it out if your still looking for an answer.

Squid ClamAV Redirector is a Squid helper script to get virus scanning for
defined extensions (for example .exe, .com, .bat ...)

SCAVR handles the request as given from Squid, downloads the URL and scans it
for known virus. If a file is infected, it rewrites the URL from Squid to a
blocked URL or to an info page with scanning results.

i can't send website becouse i should post 5 posted before but you can search in google about(Squid ClamAV Redirector )
