Yahoo browser hijacked myu google chrome browser

Hello Richard,
Thank you for reaching AVG Support Community.
We will certainly look into this and help you.
From your community post, I assume that the Yahoo browser was installed & set as the default browser on your PC, Am I right?
If no, Could you tell us more details about what you are experiencing?
Do you wish to uninstall the Yahoo browser from your PC?
Thank you.

After I installed all of the AVG protection, a yahoo default browser was somehow installed and AVG didn't protect me from this and I can't get rid of it.
