Cpanel Malware Attack Fix

Hi, i am really worried, my cpanel got attacked by malware few days ago and now some of my websites database are gone missing. When i open the site it show "Error establishing a database connection". I checked phpmyadmin and few db just not there anymore. I think its some backdoor script or malicious file hiding in public_html, maybe a fake plugin or a cron job doing this in background. I need someone who really know WHM/cpanel security, can clean the malware properly, check csf firewall and cron jobs, and try to restore my database from backup (i have jetbackup i think, not 100% sure). Please only apply if u have real experience with this, im scared to loose more data.
