Sorry if you were offended. We are a family oriented site and as such take kid safety serious. I do not know of any software that will do what you described. I use iProtectYou
on my kid's computers. If they want to visit a site they give me the url and I will review it, them set the permissions. It is freeware.
Again, please do not be offended. We are just offering advice based on the experince of all our members and what we have found to work.
