Kan ikke få startside til at virke

Jeg har et problem med min internet Explorer - den vil ikke give mig lov til at ændre startsiden - den bliver ved med, at være blank, men viser en side kaldet sp.html. Den kan jeg ikke på nogen måde fjerne (Jeg synes jeg har prøvet alt.)
Derfor håber jeg, at jeg kan finde hjælp gennem dette forum.

jeg vedlægger min HiJackThis-logfil.
