ApplicationsPort 631 is Printer Sharing. As for the other one, see below.
This procedure is a diagnostic test. It makes no changes to your data. The instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Please triple-click anywhere in the line below on this page to select it:
sudo lsof -i4:9999 | pbcopy
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting. You'll be prompted for your login password. Nothing will be displayed when you type it. Type carefully and then press return. If you don’t have a login password, you’ll need to set one before you can run the command. You may get a one-time warning to be careful. Confirm. You don't need to post the warning.
If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. Log in as one and start over.
Wait for a new line ending in a dollar sign ($) to appear below what you entered.
The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.
The Terminal window doesn't show the output. Please don't copy anything from there.

Jun 19, 2015 7:29 PM in response to Linc Davisby gregfromaldieva,It turned out KAV - KasperskyAntiVirus is what creates the 1110 and 9999 (two) ports on the loopback interface.
Thank you for the quick reply and the how-to very helpful information.
I will leave those ports alone for know, but the procedure did prove useful.

Jun 20, 2015 2:20 PM in response to gregfromaldievaby Eric Root,You might want to consider uninstalling Kaspersky as it can interfere wit your computer operation. At this time Mac anti-virus programs aren't required.
If you want an anti-virus program, try ClamXav.
