I know of no email program that spreads any virus by itself. Attachments are a different story. While this virus might be sent primarily through Outlook, it might simply be because of how widespread Outlook is.Before anyone takes exception to my statements, I have been an email administrator for DaVinci, MS Mail, ccMail, Exchange, and several others for about 10 years now. Call it my trigger point that I have a problem with blaming the email software rather than the creator of the virus.
BTW, I commend those of you who do not open attachments willy-nilly and still try to help those who don't know any better.
