Unless you really know what you're doing and looking for, I really wouldn't take chances with just attempting to clean a compromised system.
I'd backup and store the website(s) somewhere else, then create a fresh server (reinstall the OS), do the basic security-hardening steps, then install EasyEngine and whatever else you need to reinstall and run your WordPress site again.
Make sure to harden the security on your site as well to minimize chances of re-infection.
