I was hacked and tried to clean it. Seems that I was right, my Avast antivirus don´t make any alarm.
But hackers noticed, that I discovered them and they did something to block my login on dashboard, when logged in, I´m redirected to my site.
So, in wich php file (I think "login.php"), but I can´t discover any suspicious there.
Where else they can have modified a file that has something to do with loggin on dashboard??? I must act quickly before they can take care. My login.php is this; (is there anything wrong, or where do I have to look? Please I need this specific answer, no links to wp-codex)
