Error Detected dans internet explorer

Bonjour,

J'ai plein de soucis en ce moment
J'ai un message "Error Detected" lorque j'ouvre internet Explorer
J'ai des alert VIrus qui arrive de temps en temps par Avast
Et j'ai aussi des .dll qui veulent se lancer depuis un répertoire temps que je bloque

Habituellement, je me débrouille tout seul, mais là je suis aux limites de mes capacités.
Je vous joins un rapport HijackThis que j'utilise pour la 1ere fois
J'espere que quelqu'un pourra m'aider.
Merci
