btrll.com certificate message

In the last few days I am getting a popup that says "*.btrll.com  certificate is invalid" do you want to proceed, I click NO but then it just goes into an endless loop.

This is happening on 2 different comports. One desktop and one laptop. Both have Norton Security running and are Windows 7 OS.  Don't know where this came from.  

Some suggestions have been to remove via Control Panel and msconfig. But neither one of them show it listed.

How do I get rid of whatever this is?

Any help will be appreciated
