Software that interactively lies to people

All of us already know that, for proprietary (/"closed source") software, there's no way of knowing if the interfaces that we're using are telling us the truth, or not. And that, from what has been discovered, a good amount of the "privacy agreements", that big corporations present to people who use their proprietary software and operating systems, are just a joke - i.e. a huge lie.

But, what about when you have software that interactively (and verbally) lies to you, when confronted with questions, made to determine its honesty (and even tries to hide the fact that it exists) in quite a good manner, capable of deceiving the most naïve?

It's corporate lying software, taken to a whole new level(!)...

(And, I don't know about you... But, this is all starting to make me envision a near future with a type of artificial intelligence interactive and learning(?) entities, that truly deceive people, like in the "Terminator" TV series...) :)
