How can someone see my browsing history on my computer?

Question

from their home on their computer just by knowing my ip number?

Answer 1

Unless they are a really good hacker, they can't do that unless they sit at your actual PC.

Answer 2

I bet your computer is Windows Vista Ultimate and you are not set-up on that computer as an Administrator; Meaning you do not have authority to access and change certain features. Your parents.guardian probaly have those permiisions.

Vista has a feature for PARENTAL CONTROL that allows the administrator to monitor a restricted users(you) activity remotely.

Your parents are in essence watching your every move while you surf the Internet.

If they are not using VISTA PARENTAL MONITOR , I assure you that they are using some other commercially availabe application to do this.
