Device Manager Question

   When I looked in the Device Manager, I am now showing two yellow exclamation marks in the Network Adapters.  One of them is "HP EN1207D-TX PCI 10/100 Fast Ethernet Adapter - Symantec Network Security Miniport" and the other is "WAN Miniport (IP) - Symantec Network Security Miniport".  Are these something NIS has put on my system, without my knowledge?  I don't remember installing any new Network Adapters.  Since they are yellow, I guess they are not working?

  Are these anything to be concerned about?
