Norton has annoyingly CHANGED my default search engine

Well, now I've done it.

After continual pestering from Norton to add some funky extension to my browser - I caved in. Now I regret it - because Norton changed my default search engine (it was was Google) to their funky, unwanted, and annoying, "NortonSafe Search."   I want my Google search engine back please.  

My relationship with Norton is only a few weeks old - and already the hassle factor is rather high. Maybe uninstalling Norton and buying a less intrusive virus protection is the answer.  Does anyone have suggestions for a decent virus protection that isn't so annoying?   I can only use software developed in the United States.

Thanks!
