j'ai effectué tes étapes en totalité.
Et ce n'est que du bonheur quand je redemarre le pc et que le processus Iexplore.exe n'etait pas activé.
Je vous poste le dernier log au cas ou .

Je vous remerci du fond du coeur de m'avoir aidé, dirigé, et réglé mon souci.
Je vous tiens au courant de l'eradication complette dans les prochains jours.

merci a toi Jean et Moe31, vous etes vraiment des coeurs...que du bonheur...merci
