I have Windows 8.1. Clean install with no malware. I do understand that this OS is still in trail, but I only wanted to give Bitdefender a heads up on my problem. I have tried uninstalling/re-installing/repairing with no success.
The problem: Bitdefender Free Edition system tray icon will randomly (I tried to replicate the problem to no avail) disappear. Windows doesn't report any antivirus programs 'not installed' when it happens. I have to double click on the Bitdefender Free Edition desktop or start menu shortcut to get the icon to come back. Once the icon comes back, usually it takes about 2-3 hours for it to disappear again. When I open the task manager while the icon is gone, there is only one instance of Bitdefender Free Edition running (usually there is two).
