That 400 statuss output is correct. This stream of binary octets does
not make an HTTP request message, not even close.

The "problem" (if you can call it that) it that some application is
attempting to pass non-HTTP garbage over the registered HTTP port 80.
The solution is to stop that application. Squids output is the polite
way of telling it that it has to use HTTP over that port.
