 * Hello
   Between my WordPress files in root/home I have mk7zxw.php with 0 beta size.
   I do not have access to many posts and pages or even admin part of my subdirectories
   or user have access but can not login . we get 500 server error on them.I did
   all the things to solve the 500 error problem but as it seems we are infected
   by something. I am using CWP for managing the server.Thanks

 * Maybe someone tried to upload a file but the firewall blocked it and PHP only
   created it (it couldn’t write its content to it, hence it is 0 byte).
   Check your
   PHP error log, it will show why you have a 500 error.

 *   I imported the database and saw I had an extra admin called “usern1231AS231ame”
   in my main domain. I removed it. How can I clean his activity?

 * Did you run a malware scanner, like NinjaScanner ( [https://wordpress.org/plugins/ninjascanner/](https://wordpress.org/plugins/ninjascanner/))?
