Hi
For the people have a Plesk Servers you can install “Revisium Antivirus” Security extension ( Extensions > Security tab > view all > search on Revisium Antivirus) then run the antivirus after that you will see list of all the infected files inside each directory and site, then proceed with deleting all the infected ones also don’t forget to remove the infected code inside some of the files (the antivirus will guide you ). That’s all
Congrats your server now is cleaned ??
Hope this help you!
