Winrzf32.dll ?

Bonjour,

J'ai une nouvelle entrée inconnue dans mon WinPatrol.
Les recherches sur internet semblent m'indiquer que ce serait un trojan.
WinPatrol m'offre habituellement la possibilité de supprimer le fichier du démarrage, mais pas ce coup-ci.
Toutefois, il semblerait qu'il soit désactivé.

Est-ce que quelqu'un serait assez gentil pour m'aider à l'éliminer svp ?
