Vps server malware removal

My project is to remove malware from my Linux VPS server for personal use. After the malware is removed, I am not sure if I want an additional security check or not, so I am open to maybe it. I am confident that with help from the right professional, this project can be handled effectively and efficiently.

Vps is having high memory and cpu use, also high hard drive use, and seems like is sending emails, also I am not able to send emails.
