Virus Ncase

Bonjour à tous,

voila le problème :
depuis un certain temps j' ai un message d' alerte Avast sur une infection par le Win32:Trojano-803 [Trj]
je n' arrive pas à l' éradiquer directement. il me balance dans windows :
C:\TEMP\NCASEP~1.EXE

J'ai donc fait un scan avec hijackthis et voila ce qu'il en resort:
