al termine utilizza i programma AD-AWARE e SPYBOT indicati in questo articolo

sempre in modalità provvisoria fai una scansione Antivirus

quindi riavvia il computer e controlla se il problema e risolto, se e tutto OK riattiva il ripristino configurazione disattivato all'inizio di questa procedura.
