Ciao.
Non aprire un topic, in cui chiedi di analizzare il log,e un'altro in cui spieghi che non ti funziona la modalità provvisoria.
Devi fare tutt'uno,altrimenti non si capisce niente.
Scarica Combofix:
Importante: Disabilita il tuo antivirus e chiudi TUTTI i programmi aperti,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.)
Digita 1, premi Invio e segui le indicazioni.
Al termine, verrà creato un file log chiamato C:\ComboFix.txt. Postalo qui.
Durante l'operazione di scansione è importante non usare il PC e attendere pazientemente la fine delle operazioni.
Posta un nuovo log di HijackThis .
Sempre qui.
ComboFix non funziona in modalità provvisoria
