Thanks! Nice article indeed.
Makes me wonder though... the latest trend seems to be that quite a few ISPs are now offering their clients free (or low cost) av filtering done via their e-mail servers. Won't that hurt the bottom line for many of the other av companies who mainly rely upon retail sales of their boxed av packages? Hmm, guess the real money will be in server side av protection?! (then again, email protection is only half the equation--considering that you can also get viruses from downloading infected files etc)
