I ask how DOES ONE EXCLUDE THES FROM SCANNING? IS THIS THE PROBLEM THEN?
How it's actually made, changes for each and every antivirus out there. You should refer to your own antivirus documentation to know how to do it.
Some antivirus will ask you to specify the file by browsing its location, which is YourFSXFolder\fsdreamteam\couatl\Couatl.exe, others will offer you the option to "whitelist" the file directly in the virus alert window without asking were it is.
Very few antivirus products do not offer any option to exclude files and, I'm sorry, but in this case you should really switch to a better antivirus because, not letting the user to exclude files from scanning, is a very bad design decision, which makes the users powerless against false positives.
If this is your case, I suggest switching to the Microsoft Security Essentials, which is very unintrusive, it's entirely free, it allows to exclude files from scanning, and it doesn't make the mistake of wrongly identifying any of our software as threats to begin with...
