I guess what started me looking into our security (or lack thereof) setup was one of those annoying popup windows that pretends to be a virus warning.. and one that would threaten to delete all her files in 90 seconds~ Thanks, allmyvideos.net That place really gives your malware security a workout. You are right, a simple noscript would probably work but then she'd be angry.
It got her scared she was going to lose all her digital 'stuff' so I started looking for solutions and can't stop.
You wife is likely the same. She'll go months without downloading a thing and would probably never know she was in a sandbox. Of course as soon as I get complacent she'll save a new bunch of 'stuff' and then wonder where it went... That downloading to a usb stick sounds pretty good, though.
The problem is she just wants - like most office workers, I imagine, transparent protection that never gets in her way and lets her do whatever she wants. If I could train her to save only to certain places it would work, but I can see her thinking that's too much work =)
Baby steps though, at least the registry is now intact on both machines as I resist the urge to clear out the gunk. I guess I missed this article a few years back:
Why Using a Registry Cleaner Won’t Speed Up Your PC or Fix Crashes
