Sparkasse Onlinebanking "warten sie bis ihrer Computer identifiziert wird" - Trojaner?

-Christian-

Hallo,
dies ist mein erster Beitrag in eurem Forum. Ich habe mir die Regeln durchgelesen und versucht alles zu verstehen und zu beachten...falls irgendwas nicht stimmt, seit nachsichtig mit mir.
Nun zu meinem Problem:
Gestern Abend wollte ich mich beim Onlinebanking der Sparkasse anmelden. Die Startseite erschien auch ganz normal, ich habe also meine Login Daten eingegeben. Danach erschien ein komplett weisses Browserfenster mit dem Hinweis "Bitte warten Sie, bis Ihrer Computer identifiziert wird".
Heute war ich bei der Sparkasse um zu klären, ob die vielleicht irgendetwas am System geändert haben - scheint aber nicht so. Mein Onlinebanking haben wir direkt gesperrt, und nun wende ich mich an euch zwecks Problembehandlung.
