If you want to test a downloaded program but don’t want it destroying your data and sending your bank passwords to the other side of the world, you should probably test it in a safe environment that’s not connected to the rest of your home network. You can do this a number of ways; here are two suggestions:
- Download the program on a spare computer that’s not connected to the rest of your home network.
- Download the program in a virtual machine that’s isolated from your host machine.
If you don’t have a spare computer or want the convenience of testing without using a separate machine, you should use a virtual machine. In this guide, we’ll show you how to set up a virtual machine and how to isolate it from your home network so you can test software.
