Salve a tutti,
da qualche settimana sul pc di mio padre si verifica un problema simile a quello descritto in questo topic: apertura di pagine porno e ogni tanto comparsa della pagina polizia di stato con conseguente blocco del pc.
Ho letto i vari thread ed ho fatto eseguire una scansione con combofix. vi riporto i log di seguito:
