Not able to install “Bitdefender Antivirus free edition”

I had “Bitdefender Antivirus free edition” and it was working fine, but all of a sudden, it would not load up at boot-up. It would not appear in system tray.

So, I completely uninstalled the “Bitdefender Antivirus free edition” and then uninstalled “Bitdefender Agent” and restarted the computer.

When I tried to reinstall the “Bitdefender Antivirus free edition” again, it only installed “Bitdefender Agent” and said “you already have bitdefender installed” before it actually installed “Bitdefender Antivirus free edition”. So, the installation was not complete.

I tried many times uninstalling “Bitdefender Agent” and starting over again with the installation, but I had the very same problem each and every time. Is there any solution to this? Thank you.


  • Have you by chance solved the problem?

    I have the same problem and I followed the same steps that you followed. After uninstalling BD Agent with the tool everything goes smoothly. I tried to reinstall BD free and it gives me this 'Cannot Copy Installer' error.

    For the moment I have installed another antivirus.

    Hi Member's

    Kindly download Glary Quick Search from and install.

    Now, boot into safe mode ( & open Glary Quick Search and search for the name Bitdefender. Whatever result gets displayed related to Bitdefender(file/ folder) delete all of them. Next boot into normal mode.

    How to boot into Normal Mode from safe boot :

    The keyboard shortcut is: (Windows key + R) and typing msconfig then Ok.

    Tap or click the Boot tab, uncheck the Safe boot box, hit Apply, and then Ok.

    Restarting your machine will then exit Windows Safe Mode.

    Finally install Bitdefender free from

    KIndly keep me updated.
