Download "Malwarebytes' Anti-Malware" her: http://www.malwarebytes.org/ (...)
Installer programmet, start det, lav "fuld systemscanning" under fanebladet "skanner".
Bagefter klik på "vis resultater", tryk på "Fjern det valgte" og send loggen herind sammen med en log fra hijackthis.

(Husk at opdatere ovenstående efter instalationen og FØR scanning...)

Smid gerne en hijack, så vi kan se hvilke finurligheder du har kørende.

fastwrite -> Det er bedst at starte at scanne med Malwarebytes og først derefter lave en scan med hijackthis. Altså nøjagtigt, som jeg beskriver i min ovenstående kommentar.

levich - kan jeg lokke dig til at kigge os over skulderen her? http://www.eksperten.dk/ (...)

bikerbirk - sorry jeg spammer dit spørgsmål...

John_stighers: Det er sgu helt okay ;)

Så har jeg fået tid til at scanne med malware, og det har da hjulpet betydeligt! Her kommer en log fra scanningen:

Det ser ud til, at alt er som det skal være mht. virus/spyware, og du siger jo også at den kører meget bedre nu.

Du har ret. Jeg takker for hjælpen!
