Analyse log possible infection

Bonsoir à tous,

On m'a prêté un portable Asus Centrino Windows XP dont la souris et le touchpad ne réagissent pas bien (ouverture intempestive de fenêtres clic droit).

Je voulais écarter la possibilité de parasites; j'ai effectué un scan en ligne,puis des scans en mode sans échec par Avast, Spybot (2 fichiers trouvés), Malwarebytes et Smitfraudfix.

Je termine par Hijackthis, que je laisse aux internautes expérimentés (qui prennent sur leur temps) le soin d'éplucher.
L'ordi est peut être tout simplement défectueux.

Voici le copié-collé et merci d'avance pour les réponses que vous voudrez bien apporter.
