That's true DrJBHL, maybe that's where I was making my mistake, that I had the auto-update enabled, mostly because in the end I uninstalled IObit and I haven't had the Fences 5 auto-install problem again.
I'll reinstall IObit and I'll check the program settings so that it doesn't happen again, and at least it will ask me what I want to do xDDD
Very good your observation... Thank you...
Happy Christmas!!!
