AVG kills Firefox during shotdown

Hello Albert,
We regret for the inconvenience caused to you. Could you please let us know which AVG product exactly are you referring to? Are you experiencing this issue when you try to install an update of Firefox? Do you receive the update notification when you launch Firefox and could you share the screenshot ( http://avgclick.me/getscreenshot ) of the update notification if you are receiving one? Thank you.

Closing two instances of Firefox just after each other the second instance gets blocked while performing updates on close and the browser session can get lost. I couldn't even restore the session anymore. Thinking of switching.
