Tomb Raider Legend's .exe coming up as a virus

I was installing this game, it takes ages, it's really big, then right at the end NOD32 came and deleted all the .exe files. I am guessing that since this is a retail game it would be ok to exclude the tomb raider install directory from AMON. I am curious as to why it would regard it as a threat though. Any thoughts?

 

You need to tell us at least the virus name.

 

We're going to contact Eidos to get that file as it's pretty large for sending by email.

 

Yes the file comes in at 1.8 GB I think. All it says is it's an unknown WIN32 virus.
I have installed the game now. It takes 10 or 15 minutes to install. I had to do that three times before I could get it down properly. The second time I tried excluding the folder the game was beign installed in but that didn't work. So had to disable amon, install the game, exclude the files, then turn amon back on again.

 

You still consider yourself part of ESET team isn't it?
