Explorer.exe starter ikke

Efter at ha fjernet en masse virus og snavns, og derefter opdateret til SP2 og de nyeste opdateringer til XP, starter computeren bare op med et blankt skrivebord: Explorer.exe starter ikke. Igennem taskmanager prøver jeg så at starte filen explorer.exe, men får af vide at filen ikke findes!?
Alt andet ser ud til at køre fint, jeg kan sagtens starte andre programmer op, og alt ser okay ud, der er bare ingen explorer.

Jeg har så igennem Recoveryconsole fjernet SP2, da det var den eneste vej jeg kunne fjerne den, kan jo ikke starte kontrolpanel da det er en del af explorer ! ("#¤%)

Hvad gør en klog ??

Om lidt starter jeg en Repair fra Console, og pløjer det hele ned *GRR*


Her er lige en HJT log :
