Vai in "Installazione Applicazioni", e rimuovi tutte le Toolbar che trovi.


Dai una pulita (registro compreso)con CCleaner http://www.aiutaamici.com/software?ID=11223
Nella schermata iniziale di CCleaner, clicca su Opzioni e poi Avanzate, togli il segno di spunta a Cancella i file in Windows Temp solo se più vecchi di 48 ore

Conosci questo programma?
