I've seen people advocate doing all your everyday acitivites on a VM. The idea being that if you foul up a VM with a virus etc you simply revert to your last clean copy of that VM. You can also readily create new VMs for high risk activities and delete them when you're finished.

That only works if all your data is in the VM too - If the VM is using external hardware, then its data can easily become toast. Reverting the VM may get you back to a working o/s, but not necessarily good data.

I agree that if you disable all network access to the VM, i.e. sandbox it, you should be OK... should be... are your printers networked? How are you getting data on & off the VM? Using file copy? What if that file contains malware? If data is only leaving the sandbox, again you should be OK...
