With VirtualBox, you can run unmodified operating systems -- including all of the software that is installed on them -- directly on top of your existing operating system, in a special environment called a "virtual machine". Your physical computer is then usually called the "host", while the virtual machine is often called a "guest".
The following image shows you how VirtualBox, on a Linux host, is running Windows Vista as guest operating system in a virtual machine window:
VirtualBox allows the guest code to run unmodified, directly on the host computer, and the guest operating system "thinks" it's running on a real machine. In the background, however, VirtualBox intercepts certain operations that the guest performs to make sure that the guest does not interfere with other programs on the host.
To create a New Machine Open the Virtual Box and Click on New Option and Give your Specifications and install the another Operating System on your Computer .And if Virus is occurs in your Virtual Machine it is not happens to your main OS Simply Delete the Folder of Virtual Box and Install Again .
