Windows 2000 broblem

You will need to boot in safe mode and delete the registry key and service thats it is using to reset your page. Be careful editing the registry, you can really mess things up if you accidentally delete the wrong items.
Check the HKey_Local_Machine\Software\Microsoft\Windows\Run and RunOnce keys for this iwantsearch key. Also do an entire search of the registry and delete all associations of this key. Not the main key but the key that the search resides on.

Then find the services in the task manager that are associated with the search. It will probably have a funny service name. Stop those processes and run spybot/(adware removal) on startup.

Turn off system restore if it is used in your os.

Download, update, and run the following.

Hijack This
This program is useful in that it shows what is currently loading on startup. You must know what is good and what is bad. Once you check it and fix it is gone. So be sure. Items you are not sure of do a Google search for them.

Run Your Antivirus again

Download and install all OS updates.

I have had to boot into safe mode and run these.

Any of the spyware removal tools will zap that particular piece of malware.
