Someone told me that she was using a computer at a lab(connected to the internet, and a certain person she knows came into the lab and started using another computer there, and she thinks that that other person was using some computer software (temporarily) in order to spy on what she was looking up. When the computer was restarted, it acted unusually in that only a blank screen appeared for a *long time* instead of the deskop icons.I think it is plausible if 2 computers are on the same local area network. Perhaps it is something that is downloadable from the internet? If, for instance, I have 2 computers at home, both using the same internet connection(cable), and if one is connected wirelessly and not necessarily used in the same room, how would I be able to see what was going on in one of them if some one was using it and if I was sitting at the other one, and both were connected to the internet at the same time. Could anyone help me answer this question, or suggest where I could find the answer? I would really appreciate it.
