Help Please ! Rapport hijack, besoin d'aide

Please, j'ai besoin d'aide!

Sur mon ordinateur sous XP SP2 s'affiche de maniere intempestive et irregulierement la fenetre "Informations Systeme".

Il arrive aussi que l'ordinateur se mette en veille prolongee alors que j'ai bien verifie que cette option est decochee.

S'agit-il d'un virus? J'ai fait l'analyse en ligne sur le site Panda, rien trouve.

Voici mon log HijackThis:

Merci d'avance a ceux qui voudront bien m'aider!
