pierwsze co zrób to przejrzyj logi, pozmieniaj hasła, zrób kopie bazy danych i wgraj te pliki na nowo

i tak jak napisali sprawdź czy nie masz włączonych jakiś niezaufanych plugin-ów

A gdzie mogę znaleść odpowiedź co było przyczyną?

przy Wordpress często przyczyną są własnie pluginy dziurawe jak ser szwajcarski przez, które spamerzy i inni wchodzą... bo raczej atak typu łamanie hasła bym wykluczył ale warto sprawdzić logowania do panelu

przeskanować kompa bo może wyjęli hasło z ftp o ile masz zapamiętane

Czym przeskanować tego kompa?
Korzystam z Filezillii do połączeń przez ftp.
O to chodzi ---> ftp scan malware takiej frazy szukac w Google?

Czymkolwiek co przypomina AV, może być NOD32, AVG, Norton.
W każdym razie polecam również https://www.virustotal.com/#url do skanowania poszczególnych plików i url.
Dodatkowo polecam Search&Destroy - agent zabezpiecza pliki przeglądarek w czasie rzeczywistym, oczywiście przed małymi szkodnikami ale równie groźnymi

tak jak już wspomniał mój przedmówca jakimś av
