i have a fresh install of win professional im using avast free 9.0, windows firewall default, and malwarebytes free but not real-time just on demand as needed. nothing else running, i see avast has 3 active shields on and i dont see much difference in switching them on or off. and prior to 9.0 i had decent bandwith but now im not sure?
