text: how does keyloggers work? my bf put a logger on the pc and i wanna know how long it takes before he reads what ive been typin they record keystrokes (what you press on the keyboard) and then save it to a file on the computer. slightly more complex ones may then send temselves via e-mail or upload themselves to an area on the internet where your boyfriend can read it. if you let your boyfriend do this to your computer, you should ask him to take it off. if he did it without persmission, kick his *ss!
