This happens due to McAfee "Secure Search" is selected in Chrome after installing WebAdvisor. You can change the same by following the below steps. Screenshot
Thanks for the message.
I had already switched my default search engine to Chrome (once again).
I will unselect the checkbox next time - thanks a lot for that.
In any case, it is annoying that this can't be changed through McAfee settings and that the same decision must be taken every 90 days... it is NOT at all user-friendly...
