Problemer med virus og internet, start, spyware og andet

Hej. Jeg håber nogle her kan hjælpe mig med det her. Jeg kan ikke komme på internettet, da der i min startside bliver ved med at være en anden side. Dette gør at jeg får en pornoside til at poppe op hver gang. Og det er sgu ikke så skide fedt, vel?
Jeg har selv prøvet at finde lidt programmer til at fjerne dette.
Jeg har avast inde til at se mine filer igennem, og de melder at jeg har en infected computer hver gang.
Derefter har jeg downloaded et program der hedder hijackthis. Men de henviser til at jeg spørger nogle eksperter. Og det er nu det jeg gør her. Kan i hjælpe mig. Jeg har en log som fra hijackthis som lyder: Logfile of HijackThis v1.98.0
