ciao

dovresti ripetere la scansione con malwarebytes, quella che hai postato risale a 3 giorni fa

prima di scansionare il sistema, aggiorna il programma


Lancia HiJackThis -> Clicca Do a scan only -> Metti la spunta a fianco delle righe che ti segnalo qui sotto -> Clicca su Fix Checked

da pannello di controllo disinstalla la AskBarDis e le altre toolbar che hai ( se ne hai altre) sono solo fonti di attacchi da parte di virus e spyware
