Probleme virus INCOMPREHENSIBLE - hijackthis

Bonjour,
Je vous contacte pour un problème récurent sur ma machine. C'est a n'y rien comprendre. En effet, un processus au nom : motbfempn.exe prends 99 % du processus par alernance. MSCONFIG m'indique qu'il se trouve dans WINDOWS/SYSTEM32 mais arrivé dans le dossier en question, pas une trace de ce fichier !!! Je dois préciser qu'il ne sagit pas d'un FICHIER CACHER !!! Je le decoche alors dans MSconfig pour qu'il ne se lance pas au demarrage mais inutile il se recoche tout seul a chaque lancement ! Je vous joint le log hijackthis de ma machine qui, je l'avoue, n'est pas très propre !!!
