Ciao,
anche io ho lo stesso problema.
Ho già provato a ripristinare le impostazioni di chrome, a scansionare con i programmi da voi citati, ma niente. Ogni volta che riavvio chrome buyand save ritorna.

questo è il log di junkware:

Ho provato a ripristinare da un backup, ma arrivo ad una schermata in cui mi chiede di selezionare un input da tastiera, ma la tastiera non funziona O.o
Ne sapete qualcosa?

Grazie in anticipo.
