grazie: Massimiliano7757

Il log è a posto.
C'è una voce che potrebbe essere un rimasuglio, usi ancora Password Depot ? è un sw a pagamento, se non è più in uso allora fixa ed elimina le seguenti voci:
O2 - BHO: Password Depot 7 - {9F79B165-70F7-4C46-B1A5-8828E2FF21F9} - "C:\Program Files\AceBIT\Password Depot 7\pdIEAddOn32.dll" (file missing)
O9 - Extra button: Password Depot 7 - {9F79B165-70F7-4C46-B1A5-8828E2FF21F9} - "C:\Program Files\AceBIT\Password Depot 7\PasswordDepot.exe" (file missing)

Poi in avvio hai delle voci inutili, basterebbe solo l'antivirus, le altre non servono e rallentano inutilmente il pc, vedi tu. Ciao
