Just did a clean install of Windows 8.1 on a laptop. When finished, I noticed a new folder in the "This PC" section of the Windows Explorer sidebar. The folder is titled "Master" and it contains a lot of subfolders, each one titled Channels x - y, where x and y indicate a different channel range for each subfolder. None of the Channel subfolders have any content. If I check the Properties of the Master folder it shows ARRIS and Verizon Media Server.

I have Verizon FiOS triple play and, clearly, this must be related although I didn't install any Verizon software following the clean install of windows (I did choose my SSID and entered the passphrase in order to connect to the internet). None of the other Windows computers have this folder and all are running fully updated Windows 8.1. What's going on? What's the purpose of this new folder? Do I need the folder and subfolders or should / can I delete them?

Thanks for any help or advice.
