Should I change my name?

I am 21 and i have recently found all these old pictures with my name on them plastered all over the internet, i found smear pages written about me from some girl i went our with when i was 15! Along with various other non flattering images and information. Nothing is illegal or extremely vulgar, but seeing as I have my own business now I am concerned what the effects of my actions in highschool several years ago could have so I am thinking about changing my name even though I don't really want to it just seems like today if you do ANYTHING at all that it will be put on the internet never to come down, and the only way to get out of this is a name change.
