Safari Redirects to Google.com
I have found a separate post helpful for this question. https://discussions.apple.com/thread/7938840?answerId=31691433022#31691433022
One out of two of the fundamental areas of interest related to this question was answered in that post. Website blockers (from a system like Parental Controls) can cause this problem. However, I am still wondering why google.com is the site that is redirected to despite the fact that Yahoo is my search engine of preference.
To clarify the situation that occurs I will attach a screenshot of such a redirect:
