My sites cpu has been stuck at %100. I did a scan and found files infected saying it's Backdoor:PHP/EvalSuperGlobal.7725
I remove the files and cpu goes back to normal. But every few days the files are shown again and the cpu goes back to %100. I am looking for someone with the right skills to find out what is creating these files and how to stop it.
They are showing in the wp-admin folder
