There is only one way I know of to stop the damage. A physical barrier such as conduit or ducting. Its the best way to ensure cable integrity.

Saying people wont read is hitting the nail on the head. Two of the biggest problems I see when people ring for help is they fail to (1) Listen to what they have been told (2) Dont read the content on the screen. This alone proves the point that people want the technology without the responsibility of having to learn. Some comments here say "just use a Mac" but thats not the solution becuase serious attacks are appearing againt Macs and Linux. I use both Windows and Linux, and prefer Linux for ssecurity reasons, however it does require a level of education. If the computer security Industry wants to make products for the Windows based platform that will keep people happy, then the KISS principle is needed. Have a set of automatic security level templates based on Hardened, Average and Low. Users would love this. The other problem which someone else noted is firewall notifications, users hate them becuase it forces them to interact, this too could be changed tolimit the amount of feedback in to only popup when a predetermined (user controlable) threat or seriousness occurs. Thats the challenge.
