So...that shell script? The C99 shell script and the one in rdy.php both in the images folder? The entire site you had was uploaded today as well, which pretty much obliterates the possibility of being hacked. There's -nothing- you can do at this point. C99 and other shell scripts ALL put other x10hosting users at risk, and as such they are a zero tolerance permanent irrevokable suspension. We don't allow other users to put your account at risk, so we're not allowing you to put -others- at risk.
So in short, there really -isnt- anything you can do at this point. This violation is one severe enough to warrant the immediate and permanent removal of your access to the host.
