sospetto

[TaloN]

buongiorno
un aiuto per favore girando dentro il mio router ho visto queste scritte.
io non sono molto ferrato in materia, ma corregetemi se sbaglio, qualcosa non mi quadra.
iniziando dalla connessione adsl, navigo a singhiozzo
i pc connessi al router philips SNA6500 con impostazioni di base sono tre, un amico, un fratello e io.
il mio pc sono sicuro che e' pulito e aggiornato.
Ditemi sono attacchi dos vero? se si come posso eliminarli?

grazie
