What do you mean by "of course nothing works" as if i'm supposed to obviously know this?
You said you searched on the forum, and none of the forum threads about antivirus, ever relates to your problem, which is FSX quitting to Desktop with no errors.
The forum threads you found about the antivirus, were only related to the software modules not running, which results in no menus under the FSX "Addons" menu and no buildings in the scenery, but with FSX otherwise running normally.
The link is not very helpful as it doesn't mention if i'm supposed to uninstall the scenery then reinstall (which i did a few times anyway and then added the updated stand alone addon manager), or reinstall over the first scenery without again installing the addon manager and couatl. I asked for help nicely and got a very abrupt and seemingly annoyed reply but thanks for it anyway.
The link is very helpful, short, precise and to the point. If it doesn't mention if you are supposed to uninstall first, it's because you don't have to, or it doesn't make any difference if yo do. If you had to uninstall first, or if it made any difference if you did or not, the link would have said so.
And, the link doesn't say JUST that, the most important part of the two points solution was THIS one:
- If this doesn't fix your issues, or you never had any scenery from Earth simulations, please contact me in private with a Teamviewer session ID and password because I really need to check your system with it. Teamviewer can be downloaded for free here:

I haven't got any private messages from you so, but you replied here. Are you sure you read that post carefully enough ? Awaiting for your PM now.
