On the blog title and wp login I see code like this :

+ADw-BODY bgColor+AD0 black +AD4 +ADw-p … white size +AD0 4+AD4-TURKiSH HACKER +ADw-/font+AD4 +ADw-embed … +ADw-TITLE+AD4-Hacked By HaYaL-ET-06 +ADw-/TITLE+AD4 …

After browsing to find out how to solve it but still doesnt work ,
these are the steps I did :

– Uninstall and remove all plugins ,
– Uninstall and delete all theme and install new theme ,
– delete all the files in the host exception wordpress wp-content , wp – config .
– Remove .htaccess
– Upload wordpress 3.8.1 file manually with FileZilla except wp-content , wp-config, and readme

, … still no change .

I checked in the database ,..

– On wp_option the option_name column blogname I find strange code as in his title , then I change it with my blog name . I have not checked all the database because I dont know what kind of code must be found .

After that , the changes seen , codes on title and display wp-login lost .

But, the blog still like the picture on the link above . When trying to access the blog , I saw a glimpse of the homepage before layout the image appears .

– For a while I rename index.php and put a new index with the message that the blog is being repaired .

Now , I dont know what else to do .

anyone can help me, please? ?

is there any other files that should be deleted in the database?
