I’ve never had to exclude that folder in a couple of years of running Windows 10. Clearly something has changed in the OS.
Sure it has. Antivirus definitions are updated very often.
But that's not the main point. We don't suggest to add the Addon Manager "only" to prevent the antivirus to possibly block it, it's a best practice in any case, because even when something "works", the antivirus is still affecting it heavily. Each time an executable tries to open a file, the antivirus will scan it in the background, and this can have an huge impact on performances or slow down operations a lot. Recreating the airport cache in GSX when you add/remove a scenery usually takes 5-7 seconds, but if the antivirus is not Excluded this can easily go up to 40-50 seconds or even more, if you have *lots* of sceneries.
Whenever I install a new system from scratch, the FIRST thing I do is:
- Add entire simulator folder ( FSX, P3D, MSFS ) to the antivirus Exclusions
- If I keep additional sceneries installed on other drivers/folders, I also add all of these to the antivirus Exclusions
- The whole Addon Manager folder, of course.
- Every other folder that might contain executable add-ons. If you bought them from reputable vendors there's nothing to fear.
This is the only way to be sure the antivirus won't interfere and you'll always get the best possible performances.
