I am kind of weirded out. A little while ago the binocular icon appeared up top next to my airport icon. It was gray and when I clicked it it said something about Remote Desktop bur there didn't appear to be any connectivity. It seemed as though someone momentarily took over my computer screen. I don't know how this is possible though as this is my personal computer and I am on my own home network which is password protected. Is there anything I can do to make sure no one is looking at my screen?
