MSN qui te bloque?

Bonjour,Bonjour à tous, J'ai ce message: ''Qui te bloque sur MSN ? - Who's blocking you on MSN ?'' de tout mes contacts 2 a 3 fois par jour et aussi comme messagerie direct en discussion avec d'autre contacts. Comment faire pour arrêté ce genre de spyware j'imagine. J'ai fais un scan avec ad-aware et spybot et Malware anti-malware et ça change rien. Merci a l'avance.
