Not responsible for anything
Just put stuff in a box and sell it. Bad drivers, not our fault. Windows, definitely not our fault. Security, you're on your own but we'll give you a demo of MacAfee or Norton. Key logging is a feature, you might find out what your spouse is up to.
You can vet your own stuff to make sure it is fit for purpose. That being said it might pay to type in a random string or sentence and search within documents for what you have just typed. Won't catch encrypted files of course. You're on your own. Good luck!
