pc bloccato da virus

[genchi]

Ciao a tutti,
mi ritrovo con il pc bloccato da un virus dove mi compare una pagina con scritto il tuo pc e' stato bloccato per sicurezza e mi chiedono 100 euro per sbloccarlo.E' possibile eliminarlo usando malawarebyte in modalita' provvisoria o kasperski rescue?In caso potete indicarmi un sistema alternativo efficace?
Grazie

hai heccato il virus della polizia di stato... che versione hai di malwarebytes? qui ti metto l'utima https://it.malwarebytes.org/mwb-download ricordati prima di far la scansione completa di abilitare la ricerca rootkit e aggiornare. Se ciò non dovesse bastare io farei anche una scansione con combofix http://www.bleepingcomputer.com/downloa ... fix/dl/12/ ti basta avviarlo pensa a tutto lui.

Attendo i 2 log (malwarebytes e combofix).

P.s. per eliminare combofix scarica avvia http://www.geekstogo.com/forum/files/go ... rs-list-it e premi su cleanup, accetta il riavvio. ( questo passaggio fallo dopo avermi passato il suo log)

combofix si può utlizzare in tutte le versioni di Windows da vista a windows 8, allega il file "combofix quarantined files" contenuto in C/Qoobox (se non sbaglio) dopo di che puoi eliminare combofix con il tool che ti ho elencato nel post precedente.

Se non riscontri ancora problemi direi che abbiamo finito, fammi sapere.
