• Some one has gotten into my yahoo address book and is sending all my contacts spam using my email address. What do I do.

• Answer:

  HACKING PREVENTION: Someone has hacked your account and is still sending Spam to those in your address book. Each one will have a person's name in the subject line. When opened, there is a link to some advertising sight. If you click on the link, you get Mal-ware, Spyware or a Virus. 1: Do a spyware scan on your computer to find the malware which is sending those messages and remove it. 2: After your hard drive is cleaned, change your password, not before! 3. Clean your cache, delete history of visited websites and "Sign Out" of your account completely before leaving the computer. Click the "Sign Out" button. 4. If you leave it open, anyone can open and read your email. They can also go to the history function, or just hit the back button and get into your account. Never open emails from someone you do not know. That's how the hackers get your account info. Don't forget your new password though. You will need it the next time you sign into your Yahoo account.
