Cyber Security Help/Server Cleaning

I'm looking for a freelancer to help me with cyber security issues and server cleaning. Specifically, I need assistance with a web server that has been affected by a malware/virus infection. I'm not sure of the best approach for removal, so I'm hoping to find an experienced individual or team who can advise me on the most efficient way to safely restore the server to a secure state. My server is critical to my company and I'm eager to get it back up to speed as soon as possible. Any help would be much appreciated!
