有人知道这个代码病毒在PHP中是什么?

I don't know what is, I found it inside of all PHP files on my server, I think is a kind of virus or something else?, What do you think guys?. Is already on my server, inside of each PHP file on the top of the document, and down of this code start my normal code. I'll appreciate your help thanks!

    this is not the answer for your question, but since its the same issue I am having (https://stackoverflow.com/questions/24881340/malware-code-being-injected-in-my-php-scripts) (And I don't have the necessary reputation points to post a comment), here's a script to scan and remove all the php files: http://pastebin.com/JgyDZj3R

    Make sure to change {username} to your accounts username, create a file named yoyo.txt on the same directory as this PHP script and paste the illegal code in that file.

    Its best if you have SSH access since it will take a lot of time to execute depending on how many files you have.

    Hope this helps! :)

    If you have SSH access to the server, and the website isn't usually modified that much, I suggest you try the following:

    1. Log in through SSH
    2. Navigate to the website directory
    3. Execute the command find . -mtime -1 -type f

    This will give a list of all files which have been modified in the last day. This way you can manually check them and remove the malicious code blocks.

    Should the exploit have been installed earlier, you can expand your search to go further back e.g. find . -mtime -3 -type f to go back 3 days.

    Do note this is just a quick fix for a single website, chances are your server has been completely compromised, in which case you either need to do a full reinstall as already stated above, or get some professional help.
