I did according to the support guidelines and to not have problems with the anti-virus, I did its uninstallation. Even without an anti-virus on the computer, Couatl continued to issue the same message saying it had been modified by viruses. After several attempts, the solution I found was to transfer the files from the fsdreamteam folder of FSX to a USB stick that I use as a memory extension. When I play, I deactivate the anti-virus, I roll the FSX, I put the aircraft at the gate and only then I run the Couatl. Only then can I run the GSX.
