You must enable Bitdefender & Avira yourself in the 360 TS version 4.0.0.2048... I don't really know why they are not enabled by default? Memory is 24% on my system. If you have a lot of things running on your computer it will probably be higher. Oopsy...forgot to say this is the latest 360 TS Version 4.0.0.2048 I forgot to put this info in the title.
