The tutorial doesn't seem to mention scanning proxies at all, and the
word 'squid' doesn't even appear on that page. It makes claims about
what ClamAV can be used do which I think are not justified. I think
you might be a little out of your depth, but we can probably help more
if you tell us more about what you're trying to do.
You should be very choosy about tutorials like this that you find in
random places on the Internet. This tutorial gets you to install and
then run clamd, but doesn't use the daemon to do a scan! Perhaps the
author doesn't know that there's a 'clamdscan' utility. The tutorial
claims that ClamAV is used to secure filesystems. That's simply not
true, ClamAV was not designed for that purpose. The best that can be
said is that ClamAV can assist in detecting *some* potential threats.
It is a very long way from being the fire-and-forget magic bullet.
Perhaps the simplest way to secure a filesystem is to burn it onto a
read-only medium, but even that wouldn't be the end of the story. And
the next simplest way is probably beyond the skills of most full-time
system administrators (even those who are at present paid to do the
job by multinational corporations - witness the never-ending stream of
reports in the press about compromises); so you will be embarking on a
challenging journey if you want to take this very much further. There
is a lot of information in the documentation on the ClamAV Website and
it's all free to download. It's worth spending some quality time with
it, and if you don't understand any of it you can ask here.

It doesn't seem obvious to me. What is your sdb? Is there any reason
why you can't just provide an sdb with sufficient capacity?

Before you go breaking something you've hardly even got to know yet,
take a few steps back and let us know what you want to achieve. Don't
give us your proposals for the solutions without first explaining the
problems you want to solve in as much detail as you can.
