After a while of the Macbook being on, a computer appears under my "shared" list in Finder with this series of numbers and letters: brw1c3e841fd12e. It also says connection failed. How can I get rid of it? Is it dangerous? My Macbook is pretty new, like a couple weeks old and I don't understand how this computer could've gotten there. I noticed that when I turn the Wi-Fi off, the unknown computer disappears. After a while of turning it back on though, there it is again.
