Sounds like they are probing ports and concluding that your squid proxy
is "open" for anyone to use for relaying connections. You need to
confirm their conclusion and after tightening access you may want to
check if you've been blacklisted as an "open proxy".

You do need to find out why their tests say you are an open proxy.
Others may/will conclude the same thing. This is very similar to
having an open mail relay -- spammer heaven.
You can check here or google "open http proxy" for background and
fixes:

For squid specifics go here:

You probably just need to tighten up access to your squid proxy.
good luck,
