A) Not much I'm afraid. 

This week my clients have been bombarded with malware via e-mail from a variety of sources. A lot of it is getting through even layered defences. Here's a sample of one e-mail attachment, a spoofed invoice for a flight from a reputable airline, and how it scanned by the various anti-virus vendors.
