Trojaner-Board - Programme hängen sich beim beenden auf

Hallo,

mein Bruder hat folgendes Problem:
Nahezu alle Programme (ICQ, AntiVir ect.) hängen sich auf, bzw. geben keine Rückmeldung, wenn er sie beenden will. Das Problem besteht erst seit kurzem.
Ein Scan mit AntiVir zeigt keinen Befall an. Auch gibt es ansonsten keine Probleme:
