My email is being used by the latest email virus for some reason so I'm getting all these bounces from various automated mail systems that check for viruses. If you got an email from me, sorry, I didn't send it. And I don't use Outlook and my Windows is patched.
Update: News.com has the story. This thing is vicious: "The virus grabs e-mail addresses from several different locations on a computer, including the Windows address book and Internet cache, and sends e-mails to each one. The virus also forges the source of the message using a randomly selected e-mail address so that the infected message appears to come from someone else."
