My search engine is set to Google and has been for years. I do dozens of searches from the omnibox a day (IT Manager). About a week ago, I noticed that occasionally I would get a Yahoo search result page. It probably happens once or twice a day. If I immediately do the search again, I get the expected Google results.
Does anyone have ANY idea what would be causing this?
My only thought would be an extension. I've disabled the only one I installed recently, but is there any way to confirm or troubleshoot this issue?
Edit: This is happening on two PCs. Must be an extension.
