For those critical of the OP, I think they need to applaud him for his recognition he has a problem. This is akin to an alcoholic throwing out all alcohol and not going to bars. Problem is, there is public wifi where he lives. I think the best option is having someone else set up parental controls and disallowing internet access is the best option. While trashing Safari is not bad, the OP can just as easily download it. Any block he put up, he can just as easily take down. I think you need someone else to do the deed, OP.
