Thanks moderator to clarify this, I will erase the comment if its an error.
Hello Guys,Watch Out! it seems its a vulnerability of xmlrpc
if you have wp 3.5 maybe this is the cause, if somebody has another solution, please tell me, Thanks
the solution here: (read carefully)
http://perishablepress.com/wordpress-xmlrpc-pingback-vulnerability/
# protect xmlrpc
<Files xmlrpc.php>
Order Deny,Allow
Deny from all
</Files>
Any ideas about this, every day wp security shows:

and the same Ip
I don´t have a trackback folder
