Here the instructions :-
- Open Add/Remove Programs by going to Control Panel in Windows (or type ‘control‘ in the Run prompt and press enter).
- Uninstall the PDFforge toolbar and/or Search settings listed as applications using Add/Remove Programs.
- Well done! Get yourself a victory coffee for delivering your browser from Internet AIDS.
Installing PDFCreator also installs the PDFforge toolbar, which intentionally misdirects 404 URL navigations in Internet Explorer and Mozilla Firefox. Thanks to James for posting about similar problems caused by Search settings.
