I do have a minor problem downloading, that has occured regularly...

Help!

There's nothing to say, other than your antivirus is wrong reporting a false positive.
Turn off the realtime protection when downloading and installing, and configure it to ignore the following files:
YourFSXFolder\bglmanx.dll
YourFSXFolder\fsdreamteam\couatl\couatl.exe
Before turning it back on.
