Seems to be a problem related to the disk permissions settings https://forums.virtualbox.org/viewtopic.php?f=8&t=40525

From the above link

Had the exact same problem& ran Repair Disc Permissions. After this tried again to open Virtual Box. Then received message including option to download & install Virtual Box Extension Pack. Went to http://www.virtualbox.com, downloaded Oracle VM Virtual Box 4.0.6 Extension Pack (ALL PLATFORMS), installed same and Virtual Box again opens and operates correctly.
