Grazie R16, ho seguito i tuoi consigli e alla fine ripristinato configurazione di sistema.
L'unica cosa che ho eseguito in modo leggermente diverso è stato il passaggio da te consigliato :
Disistalla il programma Ask.com.
C:\Programmi\Ask.com
Non avendolo trovato tra i programmi , ho provveduto a svuotare la cartella che lo conteneva ( senza cancellare la cartella ) spero di non aver fatto male.
Gradito consiglio.
Per sicurezza allego nuovo log di Hijack
