[XP] PhiBtn.exe empêche la fermeture Windows

Bonjour
Lorsque je ferme windows XP j'ai un message qui me demande d'"arrêter maintenant" un programme et de perdre les données si je l'arrête. Il s'agit d'après le message de "PhiBtn.exe".
C'est sacrément agaçant d'autant que je ne vois pas à quel programme cela fait référence
Quelqu'un aurait-il une idée ? Je préfèrerais m'éviter le reformatage mais bon....
D'avance merci !
