How do I get rid of this Danish iWeb homepage?

Whenever I reboot my Mac (formerly 2009 13" MBP, recently migrated to a 2015 13" MBP) my Google Chrome homepage shows the following Danish iWeb help page. I no longer have iWeb installed, but I imagine it's followed me onto my new MBP via the Migration Assistant. I've verified that my home page is setup correctly in chrome and if I close the Chrome window and re-open it my home page will be correct, so this problem only occurs **once per boot**. Here's the window that I'm talking about: I've never had my Mac set to Danish, but this Mac has gone through several family members and several OSX updates through the years.
