He claims that he doesn't know how it got there and that sometimes when downloading something else, this stuff gets in too.
LOL ...... How many times have we heard that comment before ........ I didnt do anything ..........( Ya right ) ........
I would suggest to your son , that as a result of finding "STUFF" on the machine that you dont approve of ..... His access to the pc will be controlled ..... If His pc is in his room ...move it out into another area , one that can easily be monitored.
Tell him that ....you are giving him the benefit of the doubt this time .......but .....you have installed a program which will track every keystroke he makes .......and if you find any more ......the pc is gone.....
You could also set up a user account for him on his computer . You would be the system administrator ........ Then you could set the security and access features up as you see fit and he would be unable to change them.
It might also be worth passing on to your son that you didn't just fall off the turnip truck.
Good luck .......
