Your site is doing a conditional redirect which looks like a hack of your .htaccess file. Check the .htaccess file for any suspicious redirects, redirects to mayatek.info/0/go.php?sid=2. be sure to scroll all the way to the botom of the file and to check all directories for additional .htaccess files. On some servers the .htaccess file is a hidden file so you may need to select something like “Show hidden files”
