Grazie per la risposta.
Allego il log di Hijackthis.
Prima di eseguire ComboFix (le istruzioni date vanno bene anche per win8 a 64bit?), volevo fare una domanda forse stupida, ma mi è venuto il dubbio: se ripristino il sistema alla versione salvata in precedenza, mi pulisce i registri di sistema? potrebbe essere sufficiente per risolvere il problema, oppure l'infezione è più profonda? Grazie ancora.
