Norton didn't find anything new, but all the other did :O)

But I still think that there is something there because:

Everytime I start/restart the computer I get the following messege when windows start:

Winupd.exe - this component was not found
This program could not start, because cmid.dll was not found, the problem could perhaps be solved by installing the program again.
(I have translatet this message to english, so the error message isn't the exact word for word, but the basics of the error should be of use to you)

When norton start I get this message:

Notton AntiVirus has detected at virus on your computer:

Object name: C:\windows\system32\\log.dll
Virus name: Backdoor. trojan
Action taken: Uable to repair this file

Then I press th ok button, and emidiatly the same windos pop up, but in action taken it writes: Acces to the file was denied.
And I can pres the ok button, and these two windows take turns on popping up.

Further more, I have a proces in my task manager call mstasks2.exe and that occupies 99 % of the cpu, so I have the end that process if I wan't to to anything on the machene.

Hope the information can be usefull.

And thanks again
