Virtualbox startup

I have installed virtualbox, but there is now entry in Applications, I used the terminal to open it but when i close the terminal, VB closes too.
Should there be an entry in Applications or is there another way to start the program ?
I,m not asking about starting an OS in VB just how to first start the program itself

There should be one in Menu>System Tools

You should have a virtualbox.desktop file in /usr/share/applications

Hi Bill, I had not turned off the pc when i sent this, i have now
restarted my pc and there is an entry in * System Tools now and
it works
