Your account has been compromised, Yahoo strongly suggests that you change your password NOW. Then it will stop. Run a virus scan. Alert your contacts not to click any links in the message because it is a virus/worm At one time someone sent you an infected email and they didn't know. Like those forward chain mails. It latched on to your contact list.
