Re: VM's and viruses
Depending on which VM software you use, the virtual disk is usually stored as a file. Anything that happens to the guest OS will be independent of the host, meaning if the guest gets a virus, the host will not.
In VMWare, you can set the virtual hard disk to be nonpersistent. This means that anything done on the virtual machine will be lost when it is powered off. This is great for creating a sandbox for web surfing because every time the VM is restarted, it is reverted back to a particular point in time.
