Bitdefender desapear from my PC, even after reinstall still not showing

Hello Jose_C,

There are chances that Bitdefender system tray icon is not getting displayed but still the processes will be running in background. Just do the following:

1. Perform a system reboot and see whether it works now.
2. If still system tray icon is not displayed, open task manager and see Bitdefender processes are running. If it does, it means you are being protected
3. And what it does when you open the Bitdefender application from menu or desktop? Does it load?

Just to confirm your computer is protected or not:

You can download the sample test file (its safe) to check whether your antivirus program is active and running:

Thanks and Regards
