Solution to this is to reinstall the VirtualBox without Bridge network support. Here is how to do it

In the install wizard “Custom Setup” phase, under “VirtualBox Application”, there is a tab named ““VirtualBox Networking”. Under this , you will see another one saying “VirtualBox Bridged Networking”, just click the drop-down on its left side and hit the Red Cross Sign. It will disable the Bridge.
