I have moved this to the Virus/Spyware discussion board where you should be able to get better help on this issue.

I see the same mention of it on a French website presumably the same one you mentioned:

From a Google Translate it looks related:

You download software ( sweetpacks bundle uninstaller ) for disinfection and you find yourself with a PUP : SweetIM Plus it all these files that launch automatically upon start your PC and which were not present before nuwnab.exe okuoud.exe ujepke.exe udabuj.exe laelwn.exe awlanu.exe

So it seems related to this:

http://sweetim.sweetpacks.com/

I would say it needs to be removed.

Pieter,

What operating system are you running on that laptop and which security scans have you run so far? What were their findings?
