Kursk 1943 failed installation and virus

[rbbane]

I have just bought TOW2 Africa 1943 and TOW2 Kursk 1943 today from PC World, Meadowhall Retail Park, Sheffield. Both copies were brand new and unopened.

I installed Africa 1943 successfully, after entering the "key number". It then ran with no problem. (I was ready with the 1.30 patch but found that the game was already at version 1.30 without patching).

I then tried to install Kursk 1943. During the installation my anti virus program, AVG, reported that there were two threats contained in the installation files.
I had to ignor two files during the installation to get it to install at all. Then, after rebooting, I found that the game would not load or run at all.
I tried uninstalling and installing again, but with the same results.
The Kursk installation did not ask for the Key number, which is on the manual.
I found that the game was to version 1.20. So I patched it to version 1.24 and then 1.31. Still the game would not run, saying each time "The application failed to initialize properly (0x0000005)" .

I then used my anti virus program, AVG to scan the Kursk 1943 installation disk. It found that there was a "Threat" in two files actually on the disk.

1. (Bin)\Builder.exe
and
2. (MissionEditor\Bin)\SimpleEditor.exe

The "threats", according to AVG, were - Win32/Heur on both files.

I am an experienced computer user and gamer and well used to installing all types of software, including very many games, and have a powerful PC which installs and runs many modern and not so modern games with out trouble.
When I buy a game I first of all expect it to install without trouble. But I also do not expect the game disk to be infected with some form of virus.

I should therefore be very interested to hear if anyone has a possible explanation for the problems, and any suggested remedy.

I have read other posts and realise that this game has eventually installed through Steam. Mine is obviously a "non Steam" version.
Could it be anything to do with not being able to access the Battlefront web site now?
Thanks in advance for any help.
