Second time over the past year it has happened. It's to use email for spam, deleted the email account and it went into loop mode and then my account was suspended for cpu usage. here are the files that caused the issue.
It has come to our attention that your account contains malicious content:
4337 me 99.4 /home/me/public_html/rhmpanoorg/wp-includes/cek.php
906 me 99.1 /home/me/public_html/rhmpanoorg/wp-includes/checker.php
23316 me 99.1 /home/me/public_html/rhmpanoorg/wp-includes/cek.php
The first number is the process number then it shows your user name and then the second number is the % of how much of the CPU your are using. The last is the 3 processes and the files that are using that much resources.
