da qualche giorno non riesco a cancellare il messaggio che mi compare: "impossibile trovare il disco nell'unità.Inserire un disco nell'unità\device\harddisk4\DR4".
Questo avviso mi viene visualizzato ogni volta che metto su la chiavetta internet wind ed ogni volta che avvio alcuni programmi (di certo capita con advanced system care come amministratore). Non so proprio che pesci prendere, ho fatto analisi con svariati antivirus (Norton è quello che uso), con ccleaner e con Advanced System Care appunto, ma l'avviso viene sempre visualizzato.

Vi posto l'analisi fatta con Hijackthis, mi potete dire se c'è qualcosa di strano che conviene cancellare?

Grazie a tutti.

Scarica Combofix (usa Internet Explorer)

http://download.bleepingcomputer.com/sUBs/ComboFix.exe

Salvalo sul desktop. (è obligatorio)

Importante: Disabilita il tuo antivirus e chiudi TUTTI i programmi aperti,(Firewall compreso) e dopo aver scaricato COMBOFIX, chiudi la connessione.

Doppio click su combofix.exe (se usi Vista: tasto destro su Combofix.exe e clicca su: "Esegui come Amministratore" )

E' probabile che ti siano inviati messaggi dall'antivirus,(o dallo stesso Combofix) tu ignorali.

Se ti verrà chiesto se vuoi Installare LA CONSOLE DI RIPRISTINO DI EMERGENZA, clicca NO.

Durante l'operazione di scansione è importante non usare il PC (neanche il mouse) e attendere pazientemente la fine delle operazioni.
Al termine, verrà creato un file log sul Desktop, chiamato C:\ComboFix.txt.
