Marque, I’m sorry to hear your trouble. Here are a couple of simple suggestions.
(1) Use special characters and Greek letters, lower and upper case letters to make up a password for your admin login to WordPress blog as well as your control panel with your hosting company. Some control panels do let you use Greek letters. Others don’t. That all depends on the hosting company even for the control panel developed by the same company.
(2) Destroy the domain. Hacker5.com or whatever it is… Contact the domain company through which this domain is registered.
(3) By the way, you may want to back up database with phpAdmin like other guys say and then reinstall WP.
Good luck
