This account has been locked to prevent an attempted account theft.
A Battle.net account can be locked due to suspicious activity. To restore access to an account that has been locked, please follow these steps:
Step 1: Secure Your Computer
In the event that your computer has been infected with malicious software such as a keylogger or trojan, simply changing your password may not deter future attacks without first ensuring that your computer is free from these programs. Please visit our Account Security website to learn how to secure your computer from unauthorized access.
Step 2: Secure Your E-mail Account
After you have secured your computer, please create a new password for your e-mail account since it may also be compromised. Be sure to check your e-mail filters and rules and look for any e-mail forwarding rules that you did not create. For more information on securing your e-mail account, visit this Support page
Step 3: Choose a New Password
You must change your password in order to resume using this Battle.net account. Check your email for further instructions or visit http://us.battle.net/account/support/password-reset.html to initiate a new password reset e-mail.
Note that your former password no longer grants access to Battle.net account management, World of Warcraft, or any other login-protected Battle.net account service.
If you still have questions or concerns after following the steps above, feel free to contact Customer Support at http://us.blizzard.com/support/article.xml?locale=en_US&articleId=20606.
