Hard to describe in technical terms, so let me paint a picture....
You're at work surfing the net looking for a new job…..you hear your boss come up behind you….this software would allow you to hit a button on the keyboard and instantaneously close all browser windows and erase all evidence of your web browsing activity. Upon hitting the button, your screen has instantaneously switched from the job hunting site you were looking at to let's say an Excel spreadsheet or some other application.
There should be no evidence of the previous screen. That means Explorer is closed (or at least open to non-incriminating site like [url removed, login to view]). It also means that there are no left over popups and no left over minimized Explorer windows in the task bar .
This must happen instantaneously and it must work 100% of the time. Speed and reliability are key.
Lastly, this software should be undetectable to anyone who did not install it.
Can you design this?
