Removing safe search...

I haven't been using my MacBook much lately; the past few times I have used it I noticed instead of defaulting to Google to search, it is routing me to something called Safe Search for Yahoo - almost all of the results are irrelevant to what I searched for. I have checked to make sure my default search engine is google and there are no extensions listed. I did try googling this but 99% of the suggestions said to download something to remove it and I am a little wary to do so. Thanks in advance for any suggestions.
