Comment enlever trojan aspx sous XP

Hello,

Je n'arrive pas à enlever ce trojan, qui m'installe digital protection.

J'ai essayé d'installer malaware, mais a chaque fin de scan qd je fais Ok pr afficher les virus tout se ferme.
Je viens d'installer ad remover mais qui ne trouve rien, voici le rapport de scan:
