How to fix my website that have been hacked

All my websites have a spam or malware report in URL checkers for malware online.

But I cant get access to my wordpress website ( I get error 500), and wp-admin is not working.

Hello,

We have detected a cryptocurrency investment scam site hosted on your network:

hxxps://domain[.]com/wp-includes/index.html?jhBgVdSEAQZSXDRcFvgHBnjMOmmKIjnHBUgyVtFCcRESXRDCfVGBH

Would it be possible to have the fraudulent content, and any other associated fraudulent content, taken down as soon as you are able to?

Cryptocurrency investment scams are sites that promote fraudulent cryptocurrency trading platforms, either directly or by mimicking well-known news sites. These platforms suggest high financial returns, but do not pay out the amounts promised. They often tailor the content served based on the visitor’s country to provide a more convincing scam.

More information about the detected issue is provided at https://incident.netcraft.com/7123cde2b8d9/

Many thanks,

I have a droplet with CyberPanel-ubuntu… and tried to fix this with a security module called Imunify 360, but I cant install it because I need to convert Cyberpanel to Cloudlinux.

So I tried tutorial(https://cyberpanel.net/docs/1-convert-cyberpanel-server-to-cloudlinux-os/) but Terminal in CyberPanel is not working. I get this image http://prntscr.com/wb4hwt

What if I delete my droplet? the problem could be fixed?

Thanks for your help…
