<resolved> Not a programming problem but..

Hello guys
I am trying to remove some text from system.dat and user.dat files on my WIn98 operating system but it does not allow me to do so.
The reason for trying this is:

The homepage of my IE has been changed the some spyware search engine who promotes their spyware removal software (http://www.pcadprotector.cc/?qq - the nerve of these bastards is amazing!!).
I have searched the coputer and there is no text anywhere containing any word existing on the new forced homepage (so I figured it is being downloaded eveytime form their web serer) and it is correct it is comming from a server called netfinder.cc
If I disable java on the browser the spyware homepage won't show up but I get a message saying I have to enable Java.
So the spyware code is Java. How can I find it and remove it? Even the sypware softwares I have tried have not been able to help.
Thanks SW
