George,
Go read that news article from the front UT page. I've been sent the email from two unknown people. It turns out this worm reads the browser cache for email addresses and uses it's own SMTP program to mail some random file from the user's machine to every address it finds.
>I think that on two separate occasions within the past several days I've received the SirCam worm in my email. Don't really know for sure since my email provider embedded the two files as text in the email message. Both emails carried the exact same message asking me to look at the file attached. (I'll provided the exact text when I get home to-night).
