My Sisters' Laptop Security Configruation

How have you denied access to IE8? Why not Turn off Internet Explorer?
 
I was going to suggest another guide, but this would be easier and Windows Updates would still work:

Webutation ( http://www.webutation.net/ )
Norton SafeWeb ( https://safeweb.norton.com ) - Can't find standalone download
Safe Preview ( https://addons.mozilla.org/en-US/firefox/addon/safe-preview/ )

Update: Switched from Linux to Windows 7 SP1 x64.

Does anyone know a better alternative to WOT?
Any recommendations to improve my config?
