Auto logout of Gmail when closing browser -and not auto logging in next opening

Is there anyway to have Avast browser require a login to google (gmail) everytime I open the browser. I share a computer with others and anyone opening the avast broswer, goes to gmail, and it opens my account. Chrome has an auto logout feature to avoid this happening. Any chance Avast has it somewhere?
