Do I need a VM?

Do I need a VM if I’m not gonna let them onto my computer and I’m only using my computer for emails/calls? This is a dumb question but I want to make sure I don’t mess up :sweat_smile:

If you let scammers connect to your computer you need virtual machine for that. Use also vpn connection. For calls you don’t need vm.

I will often use a VM if I want to record the action. If I’m just fooling around, I boot off a read-only Linux live cd, set it up the way I want, hide the laptop’s HD, and let them have at it. Nothing they can do to harm my computer since I’m running off a live USB that resets to the way it was originally. It’s fun to watch them struggle with Linux so I get a lot of laughs.
