WordPress hacked, its always loading

Hi, my wordpress has been hacked. The problem is that is always loading, and never finishes loading the web.

I found a lot of files with this code at the begin:

$sF="PCT4BA6ODSE_";$s21=strtolower($sF[4]...

I’ve modified all those files.

They have also generated many new files with names likes “star.php”, “code.php”, “press.php”, “page.php”… All they weigh 510bytes, so It was easy to find and eliminate.

After clean all files and remove the new malicious files, my website still does not work! ??

I’ve searched base64 code in all site files and database and nothing new…

I’ve also tried the following: When I stop loading the web, I get inspected the code with firebug, and I see in the “head” section, the same two files called innumerable times:

This two files are this and this.

Can someone please help me? I’m going crazy… ??

Thank you so much!
