Ciao.
Avvia hijackthis, metti la spunta alle voci che andrò ad elencarti e con tutte le applicazioni chiuse e disconnesso da Internet,premi su "fix checked":



Quel "Pandora" lo hai installato tu?


Poi:
Scarica Adwcleaner sul desktop:
http://general-changelog-team.fr/fr/downloads/finish/20-outils-de-xplode/2-adwcleaner
Clicca sul pulsante "Elimina".
Conferma con OK le varie finestre che ti compariranno.
Il pc si riavvierà, e uscirà il log con le eliminazioni.
Postalo qui, con Wikisend.

Se conosci e frequenti quel sito puoi lasciarla.
Altrimenti la elimini.

C'è anche il servizio da eliminare:

Ciao.
