You need to remember the answer to your secret question. If you dont remember, the only way to find it out and to let blizzard release it to you is to call them.

They will ask you to provide info of your idenfication, address and everything that you registered the account last time and you will have to fax it to them. Once that's done, blizzard will send you the answer to your secret question. Then you can use the password retrieval thingy. Or, you can tell them to reset the password when u're on the phone with them. As long as you still have your email u're the only one with access to your new password.

Scan your computer for trojan and viruses. www.moosoft.com or nod32 is a good virus scanner, use it for 30 days trial~

If you don't know what is the answer to your secret question, then there's only one way to solve this, call blizzard asap. They work faster if you talk to them on the phone. Didn't happen to me, but a friend of mine got her account stolen so i dug up crapload of information on how the whole thing works.

The forums are down right now but i had this link bookmarked, it has all the info you need on how to get your account restored.
