Those three projects started in 2003-2004, more or less in the order listed. At that time, avfilter v.1 used Sophos as a backend scanner. At the time, the idea of an Open Source anti-virus package was considered ridiculous by many. In fact, distributing Sophos' include files had always been problematic, and then the whole interface was apparently discontinued in April 2014; see avfilter v.2. Meanwhile ClamAV, under the aegis of Cisco, is getting better and better.
Besides swapping backend engine, rewriting avfilter entailed a farewell to MIME parsing, a vestige of the time when scanners didn't know about email. Nowadays, scanners deal more and more with phishing, an arena disputed between anti-virus and anti-spam. Since ClamAV is an open product, organizations can build signature databases to target various kinds of malware. Sanesecurity do a good job at maintaining, distributing, and classifying some. The average rate of false positives is part of their classification. Avfilter can be configured so as to allow certain infected messages to pass, with an added header field spelling the name(s) of the malware detected therein. That way, a downstream filter can decide to accept or block based on further data, such as domain authentication. See the docs for details.
