A basic answer for amateurs and your situation:
- Read through this answer
- Contact your web host to let them know of the problem and ask for help with any parts of this answer that you don't know how to do yourself.
- Download any existing backups
- Change all passwords with your web host, CPanel, SSH access, and similar means of access. Don't bother change passwords of software installed on your website (eg. your CMS or other applications you have installed).
- Create new backups of your website, knowing that this backup will contain compromised content. You do NOT want to restore directly from this backup.
- Take your website offline temporarily.
- Wipe the server and reinstall your CMS and associated plugins from scratch
- Go through your backups and find content you can recover
- Restore site content, being very careful about what you put back. Remember that there could easily be malicious scripts mixed in with your website content.
