The most in demand tool these days is one we call the personal monitor. All you need to do is install this software on the computer that the person uses, it takes a minute to install, so you will not need to be on the computer installing it for a long time, then it hides in the background so that the person using the computer you put it on, does not even know it is running.
This awesome program gives you the power to be notified of everything the person is doing, what sites they visit, what they are saying while in chatrooms or typing on their messengers and more. You do not even need to monitor everything from a computer, you can easily install their app on your Android of Apple phone and then sit back and watch the notifications come in, you will see live exactly what the person is doing on the computer they are using, just as if you were right there beside them.
This is an incredibly powerful software and is designed for employers to use to keep an eye on their employees and for parents to keep an eye on their children while they are using the internet.
You do not need to be a techie to use this program, just go buy it from the site called Spyrix where they sell the normal version and the premium, see what features suit you best.
