Open a DOS command prompt windows (from Start->Programs->Accessories), and enter the following commands: cd "%WinDir%\System" regsvr32 /u "\Program Files\AdvSearch\spredirect.dll" regsvr32 /u "..\BrowseProxy\pluginst.dll" (The second command may need to be changed on non-English Windows installations where 'Program Files' is called something else. The third command will not do anything if the BrowseProxy variant is not installed.) Next, open the registry (click Start, choose Run, enter regedit) and go to the key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run. Delete the 'BrowseProxy' entry pointing to 'FindService.exe'. You can also delete the key HKEY_LOCAL_MACHINE\SOFTWARE\Olivia Corp to clean up if you like. Restart the computer and you should be able to delete the 'AdvSearch' folder in Program Files. For the BrowseProxy variant, you can also delete the 'Installer Class' entry in the Downloaded Program Files folder, and the 'BrowseProxy' folder, both of which can be found inside the Windows folder.
