Removing default Virtualbox guest additions?

From using the commands:

dpkg -l | grep virtualbox
ii  unity-scope-virtualbox      0.1+13.10.20130723-0ubuntu1      all    VirtualBox scope for Unity

And

lsmod | grep vboxguest
vboxguest   282624  6 vboxsf,vboxvideo

Since you want to remove these packages do as follows:

1. modules vboxguest:

   • Change into /opt/VBoxGuestAdditions-<version_number> folder

     cd /opt/VBoxGuestAdditions-<version_number>
     

   • In there run:

     sudo ./uninstall.sh        
     

2. For the guest additions unity-scope-virtualbox:

   sudo dpkg-query -s unity-scope-virtualbox
