grazie per l'aiuto.

Ho fixato i file che mi hai consigliato, ma purtroppo le funzionalitą del computer nn sono ristabilite.

Ad una seconda scansione con HijackThis v2.02 l'esito č questo:

Perchč "O2 - BHO: (no name) - {DA39029C-D291-A968-3FF4-D0990D5CB5FC} - (no file)" continua a replicarsi???
E come elimino l'utente che mi blocca alcune funzioni?
Come elimino l'indirizzamento a www.google.com?
