Ci sono un pò di cose da eliminare in particolare Browser Manager e OfferBox.
Fai queste operazioni:

Scarica Adwcleaner sul desktop:
http://general-changelog-team.fr/en/downloads/finish/20-outils-de-xplode/2-adwcleaner
Avvialo e 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.
Poi installa Malwarebytes QUI lo aggiorni e poi fai una scansione COMPLETA non veloce, elimina quello che trova, posta il suo log.

Poi rifai la scansione con HJT e posta il nuovo log aggiornato, vediamo cos'è rimasto. Ciao
