Buonasera, il mio pc è vecchiotto, ma non posso perdere alcuni programmi e riformattarlo, quello che mi preoccupa è che non riesco ad avviare Marwarebytes per una scansione e che con adwcleaner mi aveva trovato questo: PUP Optional infog. e PUP Optional legacy. uno dei due non è stato possibile rimuoverlo.
Allego la scansione fatta con Hijack portable.
ringrazio fin d'ora per l'aiuto.
