Your son? Follow the procedures in the below websites, and once
solved, you set a password but do not give it to him. How old is he?
Also, use a password when you set a screensaver.
Donna;
You have already been given good links.
But to add a little...
If someone did as your son in a business, he would probably be fired
immediately and justifiably so.
There should be an appropriate punishment for misuse of your computer.
You need to set firm guidelines probably not to indifferent from those a
business might use.
Those guidelines are important since if your son has physical access,
nothing you can do will prevent a similar occurrence again.
You do not need nor is there a technical solution to your problem.
