Email-borne viruses cost companies time and money. And so do anti-virus
applications which aren't frequently updated, or that get tricked by
very simple malware tricks. This talk looks at how to write a simple
heuristic virus scanner in Perl, which will defend against the vast
majority of current and future email-borne virus threats.

Firstly, we look at why viruses spread, and what common features almost
all email-borne viruses have. We then look for ways of detecting these
features, and then step through a few sample filters.
