All'avvio del mio pc (Windows Xp) compaiono 2 avvisi di protezione che mi chiedono di accettare l'esecuzione di 2 file winlogon.exe, consenso che io ho sempre negato.
Effettuando l'analisi del sistema col programma Hijackthis e copiando i risultati nell'apposito spazo vengono rilevati 2 virus Trojan sotto il nome di winlogon.exe che si troverebbero in C:/Documents and Settings/Utenti/Dati applicazioni/winlogon.exe... andandoli a cercare manulmente per rimuoverli, seguendo le mie poche nozioni di informatica, non trovo proprio la sezione "Dati Applicazioni".
Ho effettuato scansione completa sia con Avg che con Avirasenza risultati... come faccio ad eliminarequesti 2 virus?
Vi copio l'analisi del mio sistema:
