Il pc di un amico si è rallentato moltissimo. Ho fatto scansione antivirus ma niente di fatto. Nessuna possibilità di fare il ripr.conf. sistema. URGENTE

Ciao.
Appena puoi, aggiorna HJT, è una versione obsoleta.

Fai queste 2 scansioni:

MALWAREBYTES:

Scarica ed installa MalwareBytes:
clicca qui per il download : http://www.aiutamici.com/software?id=80346
Prima di fare la scansione AGGIORNALO. (è molto importante)
Esegui una scansione completa del sistema.
Posta il log.

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

Scarica Combofix
http://download.bleepingcomputer.com/sUBs/ComboFix.exe
Salvalo sul desktop.
Doppio click su combofix.exe (comparirà una videata.)
Se ti verrà chiesto se vuoi Installare LA CONSOLE DI RIPRISTINO DI EMERGENZA, clicca NO.
E' probabile che ti siano inviati messaggi dall'antivirus, tu ignorali.
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. Postalo qui.

Disinstalla combofix in questo modo: (dopo che avrò visto il log)
Start
Esegui
nella finestra di dialogo, copia ed incolla questo comando: Combofix /u e premi Invio poi cancella le cartelle in "C" di combofix (qoobox)

Vai in "Installazione Applicazioni" e Rimuovi tutte le Toolbar che trovi.

Dai una pulita (registro compreso)con CCleaner http://www.aiutaamici.com/software?ID=11223
Nella schermata iniziale di CCleaner, clicca su Opzioni e poi Avanzate, togli il segno di spunta a Cancella i file in Windows Temp solo se più vecchi di 48 ore


Poi posta un log di HJT (aggiornato)

ok ho scaricato la versione aggiornata. Purtroppo il pc del mio amico è molto impallato. Vedrò se riesco a postare le scansioni con i programmi indicati, altrimenti dovrò formattargli il tutto, anche se è lultima cosa che dovrei fare. Riparare e imparare a risolvere i problemi sono la cosa + importante. La formattazione deve essere l'ultima cosa da fare.
