[Win8.1] probabile ransomware

[Kis]

Salve ragazzi, sto cercando di pulire il portatile di un'amica, ieri pensavo di esserci riuscito, 2 ore di navigazione senza una pagina con la solita dicitura "polizia di stato", torno a casa sua , ricollego il portatile al router e rinizia la cosa soprattutto con firefox, con Explorer sembra reggere, ricordo che apriva spesso la home page con il nome "welcome ngix"

Navigando con il mio portatile su quella rete non ho avuto nessun problema però, non so più cosa fare, ho fatto girare hitman pro malwarebyte's premium ultima versione, hjackthis, kaspersky 2014 installato, rescue disk e winunloker da boot, niente , continuano ad uscire pagine su pagine tutte uguali con la solita richiesta di soldi per aver commesso un reato.

Combofix non gira su win 8.1

vi allego uno log di hjackthis

quelle voci inerenti file missing non riesco a toglierle, cliccando su fix in ogni caso riescono.

Avete consigli?

Disistallando firefox e reinstallandolo sembra andare ok, il router è stato resettato, vediamo se si è risolto , penso che nel pc ci siano ancora chiavi che diano problemi ma non riesco a toglierle. (quei file missing che riporta hjackthis)
