title: VirtualBox supR3HardenedMainInitRuntime! error
body: <p>I get this error every time i try to launch VBox, after some researches i found that it maybe because installing vbox.deb placed in other folder not in  /opt. (i tried many other solution like reinstalling ...).
  could any one propose other solution to me and/or explain to me how do i make my deb install in /opt folder thank you.</p>
