Hey guys, actually speaking, I am not sure where to put my question one, so here it is. I have two things to do. One thing is to keep track of the downloads across my computer and the other is to monitor who is using it. I'll explain why. I share this apartment with my roommate. He doesn't have a computer so he sometimes uses mine. I have told him not to browser those dirty websites or video as it might bring virus to my computer. These days, when I start my computer, a pornographic video dialog box will pop up and invite me to join them. I disable it in the startup. However, when I restart my computer, it pops up again. I asked him what was wrong and he looked of innocence, saying that he didn't do anything. What I want to be able to do is to see what has been done through my computer and who has used it? I'm not a super tech type so need to keep it reasonably simple. My system is Windows 8.1, Any ideas?
