Trevor, there is only one way to make a computer safe. Turn it off, crush the storage media, fill it with concrete, and use it for a boat anchor.

The whitelist must not be user writable.

No-one should ever be doing anything as administrator if they can avoid it. Installing and configuring programs (from a secure location and with valid not self-signed cryptographic signatures) is the best example of what they should be allowed. Also the user running an app should not have write access to anything other than data.
