Using avast FREE version. Am I correct in thinking that the 'sandbox' only contains sand at computer start up and any application put in the box is removed when computer is shut down? I have only seen the message once and clicked on what was recommended, without knowing what I was doing, i.e. run in sandbox, is whatever it was still there? Can I see what, if anything is in the sandbox? If so, how? I've seen something in 'Help' about applications running in sandbox having a red outline, where am I likely to see this outline, taskbar perhaps?
