Win XP: Win XP: Hilfe! Ordner lassen sich nicht mehr öffnen! Runtime error!

Hallo! Wer kann mir helfen?

Folgendes Problem, jedes Mal wenn ich versuche, einen Ordner (egal welchen) zu öffnen, kommt folgende Meldung:

"Runtime error! Programm: F:\explorer.exe abnormal program termination".
(Laufwerk F:, da F: meine Systemfestplatte ist; nicht C:!!)

Adaware, Spybot etc. haben nichts gefunden? Was könnte die Ursache sein?
