Ciao A tutti, vi chiedo gentilmente un aiuto per rimuovere questo backdoor dal mio pc.Ieri Kaspersky mi ha trovato questa infezione nel file scvhost.exe e nei relativi processi.(Backdoor.win32.rbot.bnb).
Essendo un file di sistema non me lo eliminava, e anche in modalita' provvisoria mi diceva che era impossibile eliminarlo.
Dopo l'aggiornamento e ceccata la voce elimina file all'avvio, magicamente il virus e' scomparso.Ma non ne sono per niente sicuro in quanto questa mattina ewido mi ha cuccato un trojan all'avvio, insomma la situazione mi puzza un po' cosi' chiedo consiglio a voi sul da farsi.
Vi allego il test di hijack ciao a tutti e grazie.
