Try the Add/Remove - if that doesn't do it.
Check what's running in the background - note them, shut them down.
Click Start->Run->type msconfig
Check Selective Startup - then go to the Startup Folder - if any of them have references to the filenames that you noted above - uncheck them -> click apply & then Exit without restart.
Click Start, and then click Run. (The Run dialog box appears.)
Type regedit
Then click OK. (The Registry Editor opens.)
Navigate to and delete the keys:
HKEY_CLASSES_ROOT\CLSID\{83DE62E0-5805-11D8-9B25-00E04C60FAF2}
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{83DE62E 0-5805-11D8-9B25-00E04C60FAF2}
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\
Explorer\Browser Helper Objects\{83DE62E0-5805-11D8-9B25-00E04C60FAF2}
That should help you
