Doktorn,
Hijackthis is running from :
C:\Documents and Settings\Håkan\Lokala inställningar\Temp\Temporär katalog 1 för hijackthis.zip\HijackThis.exe
please install the hijackthis in someother folder , say 'c:/hack' , and then post your log. This is important.
and btw, you need to install some patches for Internet explorer. Its pretty old. Check windows update site for any critical updates and install them
