Salve, da un pò il mio portatile va lentissimo e si blocca quando utillizzo Firefox e carico più di una pagina web. Volevo sapere come mai.
Questo è il mio log di HiJackThis:

In più ho una chiave di registro del software della Apple obsoleta che non riesco a cancellare... ho disinstallato tutti i programmi della Apple.

Inoltre avevo il problema della toolbar di Conduit di cui ho fixato la voce con HiJackThis e volevo sapere se ho eliminato il tutto completamente

Grazie
