Hi jornsen, "Not so cold Northern Europe"...lucky you! Here in the absolutely unbearably cold midwestern US we are freeeeezzzzing...right now temp is 14 F or -10C....windchill is below zero no matter how you say it!
I am at somewhat a disadvantage here as some of the programs you have running I am unfamiliar with, though research says they are ok.
I don't see much in your HJT log except this one which I could find absolutely nothing about;
O4 - HKLM\..\Run: [After] c:\MNet\after.vbs
Do you know what this is?
Do you know; stibo.com ?

You show some items running at Start up which can easily be run manually but other than that I don't see much there except some clean ups.
In the uninstall list I don't see much either. Few programs I had to look for but they seem on the "up and up" also.
A few "file missing" entries in your HJT log can be cleaned with another run of the scan but wait for PP to check back after he looks at the logs too.
