Since update to the latest version, my computer is slowing down substantially. Especially when I open Outlook or open a browser (Firefox or Chrome), the power usage would jump to as very high and the CPU would be up to 60%. Generally the CPU would be around 30% or 40% when I did not have anything open or running. I am running Windows 10 prof and I am a paid customer of Kaspersky Internet Security. Please advise how to fix this problem.
