Exactly.  And with Klez it goes further than that.  Klez take advantage of
an specific exploit that is unique to Outlook.  In fact almost all of
these do. Klez for instance uses an exploit that doesn't even require the
receiver to open the email in order to be infected.  That is just wrong.
Avoiding Outlook will solve 90% of these things since they mostly live off
of Outlook specific exploits.

Avoiding ISPs that don't do virus scanning will avoid 100% ;-]
