So, long story short, a while ago I figured out that my computer was being monitored through the Apple Remote Desktop thing and I'm interested in finding out how to prevent this from happening again (this is silly, but I can't write when I think I'm being watched, so this situation hasn't helped me much). I went into System Preferences and looked at the Sharing options. While I turned remote login off, an "unknown user" is still listed as having access to this ability, and I'm unable to delete it. I tried to disable the Remote Desktop through the Terminal using this guide but I wasn't able to type anything into the screen (I suspect my on ineptitude for this one...). But basically, how can I prevent people from externally monitoring my computer and what are the processes that would show up in Activity Monitor (aside from AppleVNC and ARDagent) if someone were doing so? Thanks!
