Which are exactly the text you're writing down on the Exclusion list and which list you're talking about (on-access or on-demand scanning)?

       I opened avast on the toolbar... went to program settings - Exclusions- Hit browse-Local Disk C-Program Files-Activion-Call of Duty-4 Modern Warfare-Put a check in the box,="C:\Program Files\Activision\Call of Duty 4 - Modern Warfare",-Hit OK and it apears in the Exclusion.

Got similar, in my big fish games, but nothing else I scan with comes up with a virus or worm. Does this happen often, as I have only just changed to Avast, but if I can't play my games etc, I think I will revert to Nod32

It's a false positive that will be corrected in next virus database update (if it wasn't already).

[Klinger]

Because this file is not just in the COD4 folder but in many you need to add the exclusion as *\pnk*.sys

I hate using such a wide exclusion but it does work and COD4 will work after adding this.

Just be glad you guys can still at least play.

I've had to completely rebuild my machine due to issues with Avast vs. Punkbuster (in conjunction with Rainbow 6 Vegas 2 though).  Totally corrupted my registry.

Yes, I've successfully recreated the error (by using System Restore points to go back to pre-install of Avast).  It is clearly an Avast vs. Punkbuster issue.

Used Avast for quite some time now but looks like I will have to find something else.

Are you using the last avast version? (4.8.1227)
Did you just try using the Exclusion lists (on-access AND on-demand)?

So avast can't be detecting it...
Maybe you could try to disable rootkit scanning for a while, IF YOU'RE SURE THE FILE ISN'T A ROOTKIT.
