TR/Crypt.ZPACK.Gen

Bonjour, je n'arrive pas à me défaire de ce cheval de troie.. J'aurais bien besoin d'un petit coup de main !
Voici mon alert Avira : C:\WINDOWS\Temp\qoru.tmp\svchost.exe Contien le cheval de troie TR/Crypt.ZPACK.Gen.
J'ai beau essayé de le supprimer rien n'y fait..

Voici mon analyse RSIT (log)
