Welcome to BC nisse
If you go to this link
and read it very carefully, then post it in the HighJackThis Fourm
we can start helping you. Once you have posted your new topic in the HJT Forum please do not reply to your own topic until a HJT Team Member contacts you. They look at the replied left. If the see a topic with anything other than 0 they will past over it believing another HJT Team Member is assisting you.
Once they have reviewed your HJT Log they will contact you with a fix. This will take a little while since every computer is a little different, every solution is a little different. The key is to be patient and know help is on it's way.
Good luck, and Merry Christmas.
