Latest Update Glitch
I had an update to version 18.104.22.1684 about an hour ago (restart needed and done). There was a scheduled quick scan run a few minutes ago followed by a warning notice ( see insert).
The BD system tray icon greyed out and said "Bitdefender services are not responding - please restart your computer". After that restart all shows normal.
It may just have been a glitch but this is just a FYI post.
