• Answer:

  Your account has been compromised, you may have gotten a email from someone on your contact list like a forward, joke, and a virus was attached to it. So now it is sending to all your contacts. Yahoo strongly suggests you change your password now and do a full virus/malware scan. The emails that your contacts are getting most likely have a link to click, it's a virus. It would be a good idea if you could inform them and tell them not to click the link. And also let them know you didn't send it. They should do a virus scan also. The worm gets into the C files and works slowly through everything until they can't use the computer. I speak from experience. It will end up with nothing but pop ups all over the screen. It will ask for a credit card number and say it will clean it up. It's a scam to get the number. I didn't fall for any of that, I just shut it down and took it to the geek squad. My virus protection didn't see it or find it. I have a better one now.
