I am running Online-Armor V18.104.22.1682 as part of my security protection. When an upgrade to OA is released, OA downloads and installs the update. Then it requires a reboot to bring in the new software update. AppDefend does not detect the change on the reboot and any subsequent reboot. If I manually shutdown OA totally and then restart it, AppDefend issues its MD5 change alert at that point. This seems to me to be a substantial security hole in AppDefend.
