Does this mean that if an employee of mine clicks Yes or Ok on the sneak-wrap agreement and I discipline or fire them for clicking on that I as an employer am still held to the terms of that agreement?

And does this mean that if I have an employee of mine sign an employment contract that states that they are not authorized to enter into any contractual agreements on behalf of my company and I post a policy on my company's web site to the effect that no employees of the company are authorized to enter into any contractual agreements on behalf of the company and an employee clicks on that button agreeing to install the spyware on my computer I'm still going to be held to the sneak-wrap agreement that the employee "agreed" to?
