Yeah! Add to this unsolicited, unnamed e-cards, and UPS "delivery not possible" e-mails (when you haven't posted anything!!). We got a dose of Antivirus XP 2008 from one of these, along with various other malware!
Mailwasher is a good program to have in order to have a bit of a look at anything suspicious, before it gets into your e-mail program.
Cheers,
