Warning: Visiting this site may harm your computer!
The website at www.yoursite.com contains elements from the site domainameat.cc, which appears to host malware – software that can hurt your computer or otherwise operate without your consent. Just visiting a site that contains malware can infect your computer.
Then, probably your site has been infected with malware. Ok first things first, be cool and dont panic. This could be resolved.
If you open your FTP and closely check your PHP files, you will see some lines of code on top of the page that starts with eval(base64_decode(.............................
index.php could be the file affected or it could have affected almost all of your php files.
You will have to remove these lines of code from your files. If you have to do manually, it will be a nightmare.
So just follow these steps to do it automatically.
1. Copy the below code and save it into a file. And name it as 'fix.php'.
$dir = "./";
$rmcode = `find $dir -name "*.php" -type f |xargs sed -i 's#<?php /\*\*/ eval(base64_decode("aWY.*?>##g' 2>&1`;
echo "Malware removed.<br />\n";
$emptyline = `find $dir -name "*.php" -type f | xargs sed -i '/./,$!d' 2>&1`;
echo "Empty lines removed.<br />\n";
2. Now upload this file to your website. (save it in the folder where your index.php file resides).
3. Open your browser and call this file (eg. http://www.yoursite.com/fix.php)
Be patient, depending on your site, it may take very long. That is why the time out limit is set to unlimited in the above code.
Be sure, all the affected files will be restored back to normal.
What the above code does is, to search for all the php files that containst the infected code and deletes those lines. Then the emptyline code removes the empty lines from the file as well.
Cheers. Your site is now restored to normal.
