Questions about one of your game files.

[KOOLLAYD]

Just curious what does the dsetup.dll do exactly? I realize some files pop up as false positives and all, but I added it as an exception on avg and it had to be done under the identity setting which was odd to me and sadly I have mcafee live safe which has no option for exception I am finding out. So I am curious what this files does and why is it unable to be coded to not ping your virus scanner? Also why is it even needed at all? I mean I ask cause I can play other servers no problems, but been wanting to check this one out and just trying to understand why it's set up the way it is and what this particular file is even for? Not implying anything, but am wondering why it's set up to be such a pain in the behind.
