I noticed that certain words get hyperlinked on websites

I have noticed that certain words will get hyperlinked on searches, websites etc. - the word is usually highlighted green with 2 underlines. This is happening on my website and others as well I go to. Even when I searched within your help section it happened. If I turn off Java script (this is a word that will be hyperlinked) it stops but if it is turned on then I can not stop this from happening - I'm hoping you can help words like save, audible, java etc. will be hyperlinked to sites I don't want and since I have a website I would rather stop this from happening to my visitors. Please help me stop this without having to tell my visitors to turn off their java script.
