Virus, trojan ou processus normal

Bonjour,
Mon firewall bloque actuellement une tentative récurente de communication sortante vers l'adresse IP 64.246.13.10

Le processus en cause est SVCHOST, mais bien sur, comme c'est le thread DCOM, c'estassez normal.

Ce qui m'inquiète, c'est qu'une recherche sur cette adresse ne renvoie que des références de banissement de forums pour SPAM

Enfin et pour être complet, tout les programmes de nettoyage, antivirus, antirootkit, antispyware, (en ligne ou téléchargés) ne trouvent rien d'anormal.
Système WIN XP Média Center (SP )
Kerio
NOD32
Adaware
AVG antirootkit
AVG antispayware
Ccleaner
Sophos
