Change in system files

Question

Hi, My AVG-Free Anti-virus is showing a change in a few system files after I updated my computer with Windows Update. The following files have been changed: kernel32.dll user32.dll shell32.dll ntoskrnl.exe At first I thought it was a virus so I completely reformatted my computer. But after doing that and performing windows update I again see the change. Could you please tell me what this is possibly and whether it is really an infection? Thanks, Rajneesh

It is completely normal for AVG to report that these systems files have "changed"...

Windows Updates may in fact change them to the latest version.

As long as AVG doesn't say they're "infected", you're okay.

I'll try to include an AVG reference link in a moment....

EDIT: There are several references to this at the AVG-Free forum... here's one:
