[Kaspersky]Civ 4 acting like a rootkit

[Zulgrib]

Hello

Kaspersky actually report that Civ 4 acts like a rootkit :
It tell that there's file hidden from the user.

What does it means ? It means, even if you display system files and folder, thoses files won't be shown.

That's why i'd like to know a way to unhide thoses files

C:\Users\[Name]\Documents\my games\Beyond the Sword (everything there)

Yes, that's a lot of files, and normal ways won't do it

Best regards

Edit : Actually checking with Kaspersky lab if it's a problem from Kaspersky or not.
