Gameguard and wuauclt.exe error messages

I have some problems with game guard since C4

Problem 1)
Dont know but I have a problem on all my PC with an error message about wuauclt.exe (Windows update component) .
The irritating thing is that the error message forcefully minimizes the game and this happens frequently.

Problem 2)
McAfee Virus scan 8.0 detected:
C:\WINDOWS\system32\wuauclt.exe:C:\Program Files\Lineage II\system\GameGuard\npggNT.des:GetProcAddress

Detection type is Overflow and not Virus.

I use:
McAfee Virusscan 8.0 Enterprise edition, Latest virus definition
Zonealarm software firewall (Latest version)
Netgear Hardware Firewall.

Anyone with the same problem?

Nice to see McAfee is on top of things at least :D

If you haven't yet done so, i would contact support.
