Hello,
You did good in asking here. I will try to help you.
From what i hear it sounds like you are infected with a harmless but extremely irritating viruslike thing that directs all your search results and links to the same page. They want you to pay, aka they want your cash. Dont give it to them.
Luckily many before you have had this same problem so simply googeling will help you to remove it.
please check the different search results you see when following the links below and see if you can find a solution to the problem that way
