VirtualBox supR3HardenedMainInitRuntime! error

Question

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.

Like described at https://www.virtualbox.org/ticket/16759. This fixed my problem (virtualbox 5.1.26r117224, kernel 4.10.0-33)

sudo chown root:root /usr 
sudo chown root:root /usr/lib 
sudo chown root:root /usr/lib/virtualbox
