while scanning my laptop for virusses, using the latest AVG-edition, I get the following result:

"results/infections:"

kernel32.dll changed

user32.dll changed

shell32.dll changed

ntoskrnl.exe changed

is that normal ? I only started using AVG recently, so i am not very familiar with the program (and I am a computer dummie anyway).

nobody ?

Yes it's normal. Read an explanation of this somewhere, don't remember why it's reported as changed, but it's normal.
