Le retour de la souris qui rend fou

Bonjour à tous.

Je m'adresse à vous en désespoir de cause pour essayer d'éradiquer un problème de souris qui rend fou.
Après quelques semaines d'inactivité, j'ai la surprise en rallumant ma machine (sous XP) de constater que le curseur de ma souris est comme aimanté dans un coin précis de l'image la rendant bien sûr inutilisable.
Trois antivirus, à savoir AVG, Avast et Panda n'ont pas résolu le problème qui, toutefois, ne se produit pas en mode sans échec.
Voici le log HiJackThis de l'affaire :
