When an update is installed that requires restarting one's computer, it doesn't work to shut down one's computer and turn it on again (i.e., do a cold boot). A notification persists that the computer must be "restarted" from within Bitdefender's notification. This is not only odd but unlike any other software I've ever seen - and, I believe, unlike the protocol for Bitdefender itself as of a couple of years ago. Any cold or warm boot should be enough to install the update.
