SQUID + antivirus content filter

[Vladimir Dvorak]

Hello *,

I would like to secure network against "themselves" with proxy and
antivirus solution.

My prerequisities are:
    SQUID, CLAMAV

What software would you recommend for such things ? ( I unsuccesfully
tried Viralator in combination with SquidGuard. )
There are other projects like Dansguardian or squid-vscan (which is
neccessary to patch squid sources and this is the last step on my
production server ).
Do you know some good howto, solution ?

Thank you,

Vladimir
