This one's permanent both for possible copyright infringement, and a confirmed presence of the c99 webshell script. The script itself appears to have self-terminated after being ran, however the scanner -does- show a valid kill log for it, complete with the original source of the file which was located in c99.php.
As such the file is confirmed to have been present at the time of the suspension, and thus this is not one we can unsuspend.
