Sei infettato da OfferBox, poi sei pieno di toolbar inutili e ci sono troppe voci in avvio.
Prima operazione da fare, vai in Pannello di controllo>disinstallazione programmi, cerca OfferBox e lo disinstalli.

Poi fai questa scansione:
Scarica Adwcleaner sul desktop:
http://general-changelog-team.fr/en/downloads/finish/20-outils-de-xplode/2-adwcleaner
Avvialo e clicca sul pulsante "Elimina". Non cliccare su cerca.
Conferma con OK le varie finestre che ti compariranno.
Il pc si riavvierà, e uscirà il log con le eliminazioni.
Postalo qui.

Poi fai una pulizia con Ccleaner compreso il Registro, sempre in Ccleaner vai in Strumenti>Ripristino Sistema, seleziona tutte le voci tranne l'ultima che non è selezionabile e rimane, poi clicca su Rimuovi.

Rifai la scansione con HJT e posta il log aggiornato che eliminiamo altre voci.
Intanto dimmi se il pc se spegne ancora da solo. Ciao
