Ironic timing… As I’m working from home today between vigorous attempts to clear the sinus infection from my head, I get a new virus alert in my mail about Mydoom.
Why We Are Issuing This Alert
W32/Mydoom@MM spreads through e-mail. This worm can disguise the sender’s address, a tactic known as spoofing, and may generate e-mails that appear to have been sent by Microsoft. Many of the addresses Mydoom uses are valid addresses that are being spoofed for malicious purposes.

To which I can only add: be careful out there.
