I wouldn't be that worried on my home environment as I'm not that much of a target and am fairly wary of dodgy emails, but I'd prefer it if more major companies with expensive stuff that can be stolen take computer security a lot more seriously.<p>For example having white-listed software only able to run (of course engineers need to install stuff all the time so they might have to be a different case, but joe bloggs shouldn't need anything new - it can be assessed by security before installing).
