The following areas are common to both compact and advanced views:
Compact View presents a simple, easy to interface that allows users to quickly launch key tasks and gain an immediate overview of the security of their computer. On the left, there is an instant virus scan box into which you can drag-and-drop files, folders or drives. If you flip this box, you can drag-and-drop programs here that to run them in the sandbox. The pane on the right displays update status and real-time protection status. Clicking on the real-time protection status will flip the pane and allow you to switch individual security components on or off.
