Please clarify, when your computer loads are you then *clicking on* Chrome, and a Yahoo webpage appears.
Or is it appearing automatically on loading?
I suspect, as Dave says, you have Chrome as your browser, but it has been set up such that yahoo (which yahoo webpage appears?) is the homepage used.
set chrome homepage
for instructions on how to change this.
You should not need to uninstall anything.
Please advise back on progress.
Good Luck - Keep us posted.
