I found AdwCleaner to be awesome, thank you very much! But I also found that even after running it, if I reinstalled Chrome, the speedial redirect would be reinstalled.
I found the speedial browser redirect also inserts a key into the Windows registry that causes Chrome to reinstall speedial whenever Chrome is reinstalled itself.
Details here:

The key on my Win 7 / 64 machine is
HKEY_CURRENT_USER\Software\Google\Chrome\Extensions\bakijjialdiiboeaknfpmflphhmljfkd
Thanks, i added the software to my website with the official link : http://logiciels.org/adwcleaner/
