I've previously recounted my struggles against malware that got on my machine, I think, because of Mrs. PTravel's surfing. As some of you advised, I'm in the process of setting up a virtual machine on my Windows 7 to computer to run a copy of Windows 7 that will be Mrs. PTravel's computer.

I just want to make absolutely sure that, whatever she does in her sandbox, it will not do any damage to the real PC's data.
