Kalpik.

IE 7 comes with a pop up blocker which in enabled by default. It will not install any application without notifying the user. If this happens your little cousin will sure call u, trust me.

2nd, if it is an OEM PC it surely comes with some sort of security suite which now usually comes with Anti-Spyware etc.

If it is self made PC or assembled PC then who ever installed Windows whether legal or illegal on it, must be wise enough to install an antivirus on it if he is not going to use it himself.
