I am sharing a computer with my roommate and it is getting very old. He makes comments about what websites I visit by looking through my history, and "says" he might just put something on there to record my keystrokes. Since I cannot kill him, I must look to protecting myself on the computer. First, if he did put some kind of keystroke recording program or any other program that would monitor what I was doing on the computer, is there a way to find and remove it? Or, if I cannot remove it, at least know if there is one on here. Also, I use Firefox and I used to be able to go to tools/privacy tab and select clear data, and this would remove everything. Now for some reason it will not clear the history in the address bar at the top of the page. When you click the down arrow it will show recent history. So, any suggestions on how to clean the computer so that he can not see what sites I have been on. Oh, and yes there are pron sites I would rather him not see, but there are others like bank, credit card, places where I purchase stuff, etc. Any advice and or suggestions would be greatly appreciated.
