My computer is used by my kids who are in 10 to 15 years of age. I want to monitor that what they do in my absence. I want to see that when they turned on or off computer. What sites did they open. With whom they did chat. Screenshots after every x minutes etc.
I do not necessarily want that this info is emailed to me or their passwords are saved. I just want to monitor their activities.
Please suggest me some good freeware software that can log everything in my computer.
