This has popped up several times i do not know what it means. I always just restart my laptop because I'm not sure if it is a virus or not. Thank You.Screen Shot 2015-09-11 at 12.35.14 PM.png

    It's the system telling you it's seeing multiple instances of a mac with that name on your network.

    The message is from the OS, it's not anything virus or malware

    If you only have one computer on your network some users report of turing OFF home sharing, rebooting your router or Airport base station can correct it.

    An Apple TV or another device like a Time Capsule or Airport base station can act as a 'bonjour sleep proxy', that means these device names get cached on the local network. The names are used to point to shared services on your devices.

     

    Reboot them all, also install any software updates to all Apple devices to hopefully resolve this, early 10.10 releases seemed to have this issue.

    There are several possible causes for this behavior.

    1. Two (or more) computers on the local network have the same Bonjour name, such as "X's-MacBook-Pro.local". Resolve the name conflict by renaming one or more of them in the Sharing preference pane.

    2. You have two physical connections to the same local network, probably Ethernet and Wi-Fi. In that case, either disconnect the Ethernet cable or turn off Wi-Fi.

    3. A Mac wakes from sleep due to network traffic. This is a bug in OS X that may only affect some models. You can avoid it as follows:

    Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter  tab, if there is one. Uncheck the box marked

              Wake for Wi-Fi network access

    if it's checked.

    4. A device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.

    5. A third-party wireless router has incompatible settings or firmware. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.

    6. If the router is an Apple device, it may need to be restarted.

    7. A Bonjour device on the network is misconfigured or malfunctioning. Finding out which is a process of elimination.

    8. There is more than one DHCP server on the network. Typically, there would be two or more wireless access points configured to act as routers.

    9. See this support article. The article refers to OS X 10.10 ("Yosemite"), but it's applicable to all versions of the OS.

    10. Back up all data. Make notes of your settings in the Network preference pane.

    Triple-click the line below on this page to select it:

    /Library/Preferences/SystemConfiguration

    Right-click or control-click the highlighted line and select

              Services ▹ Reveal

    from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.

    Restart the computer and empty the Trash. You will need to recreate the network settings.

    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

              Go ▹ Go to Folder...

    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

    If the recommended solution posted here doesn't work for you it means you have a different problem.

    You are not talking directly to Apple on this site - this is a user support forum. Contact Apple directly if you think they can help - make a genius bar appointment or use Twitter…

    Otherwise make your own thread & ask about your issue - Logic is not related to the original post so it may not be at all relevant to this issue.
