I am fully aware that Oracle bought out Sun a short while ago.
However, the latest version of Virtualbox (v3.2.4) was released on 7 June 2010 which is well after Sun's being devoured.
On all my systems where v3.2.4 is installed, the installation is put into a Sun directory/folder. Not an Oracle one. There are no Oracle directories/folders
on any of my systems.
