You need to load windows in safe mode and edit the permmisons of mshtml.dll in the system32 directory so only your acount can read it, there by disabling IE for every one except you. YOu edit the permmisions by opening the perperties of a file open the security tab, click advanced, uncheck "Inherit from partent" then remove all groups and users. Then click ok, now in the properties windows click "add" and then add your user acount to the list and click OK. Now IE will not work in any user acount ecept your own.
