I was just wondering if there is a way you could add a password so when someone wants to install a program on to this computer it would ask for said password first.You see, I have kids who like to install virus-infected programs and files on to this computer.1 person needs an answerI do too

You migth consider to use Windows Live Family safety:https://fss.live.com/Default.aspxWhich is parental controlAlso you could create another account in Windows for them and put password in your admin account(make sure to create password recovery disk when you create user account during setup password ) and then another user account they could NOT install anything.
