Somebody have been sending out emails with my address as the sender, emails containing the annoying and widespread worm SOBIG.F. This morning my mailbox was stuffed with alerts about emails stopped due to attachments containing this virus, and a few emails alerting me that my address had sent out this worm. I am checking my own email and computer right now, and the updated virus control (Norman) has not found anything yet. It's unlikely that any genuine emails from me contain the worm: I am checking and rechecking. But if my email stands as the sender of a wicked screensaver: DON'T open it! I promise you, I don't have wicked screensavers on the computer. They are all running in my mind.
