It is a dynamic IP.
I dropped my current IP and reconnected with a new one. It's still doing it.
There are 3 computers on my network. None of them have spyware/adware and the packet logs are clean. It's not me.
Out of frustration, I installed the Add Search Engines extension in Firefox and added Bing, since it's close to Google in it's comprehensive search results, and made it the default search engine.
