Remotely spying on someone else’s computer is not only bad but you can even go to jail because it is a federal crime to hack someone else’s gadget. There are only few specifics that monitoring someone’s computer can be legal if you have permission to remote someone’s computer like if they need help for software that is not working in the computer and if you have to track your kid’s activity in the computer.
There are 3 ways though to track someone else’s computer, I won’t give full details on how to do it. I don’t want to get involve in those acts. You can search it if you want. But here are some:
Determine what and want to track
Choose the right software
In choosing the right software make sure that they don’t contain virus otherwise you will end up being sorry because your computer is already infected with virus.
