Someone is pretending to be me on the Internet, should I change my real name?

OK, so here's the story - some of my high school bullies are impersonating me online. My name and surname combo is unique, there is no other person named like that in the world or in my small European country. Anyway, I don't want any prospective employees or friends to see those things about me when googling my name.

This being Southern Europe, police laughs at you when you mention online abuse and I believe changing my name would be easier despite having to change other documents apart from my ID. What would you have done if you were me?

I tried searching for similar stories online to no avail.
@Franco, thanks for your reply, I know all of that. However, the matter is my online reputation is like ruined forever because of those people. I am sure many prospective employers google candidate names.
