I recently found undesirable pictures on my sons pc, obviously to get these pictures he had to visit websites id rather he didnt. Im after something that will restrict his access to sites like that. I can block url's within my router but i can only block a max of 10, without knowing which sites he's visiting thats not good enough. Are there any programs out there (free preferably) that would allow me to do this. I would also (if possible) like the program to run from my pc and have the facility to block what he looks at on his. Ive spent hours "googling" but havent found anything that i like. Any suggestions would be great
