Someone has hacked into my email address book and is sending spam to addresses from my book. How can I stop this?

My email that was broken into was [email protected] and the alternet email address was [email protected]. My password and alternet email address was changed I think he might of even closed the account I have a lot of important contacts on that account it there any way you can reset the password...

Is there any way you can reopen my account and reset my password for [email protected]

On the tool bar if you go to Intenet Options and to Programs Under which service does windows use for each Internet service how do you add verizon to the email user?
