How can I install bitdefender antivirus?

Question

Can anyone tell me how to install Bitdefender antivirus from terminal if it's possible? I am using Ubuntu 16.04.

Answer 1

It is possible to install BitDefender antivirus via the terminal. You need to first add the repository by doing

sudo apt-add-repository "deb http://download.bitdefender.com/repos/deb/ bitdefender non-free"

Next, get and add the repository key

wget https://download.bitdefender.com/repos/deb/bd.key.asc
sudo apt-key add bd.key.asc

Then

sudo apt-get update

Finally install by doing

sudo apt-get install bitdefender-scanner-gui

Once BitDefender is installed you can launch it with the following command:

/opt/BitDefender-scanner/bin/bdgui

---

Troubleshooting

If BitDefender fails or crashes when trying to update virus signatures, you can try the following steps taken from here. One additional caveat to this answer is that you may need to wait at least 1 hour from your last attempt to update using the GUI. The application warns about not checking for updates again within that time frame.

sudo touch /opt/BitDefender-scanner/var/lib/scan/bdcore.so.linux-x86_64
sudo ln -fs /opt/BitDefender-scanner/var/lib/scan/bdcore.so.linux-x86_64 /opt/BitDefender-scanner/var/lib/scan/bdcore.so
sudo bdscan --update

Now it may show 0 signatures. However, after your first scan, it will display the correct number of signatures.

Answer 2

See the Ubuntu page on this: https://help.ubuntu.com/community/BitDefender.

It might happen that the packages repository won't be accessible for various reasons (e.g. The repository 'http://download.bitdefender.com/repos/deb bitdefender Release' is not signed).

The alternative is:

download and inspect http://download.bitdefender.com/repos/deb/dists/bitdefender/non-free/binary-amd64/Packages file which would contain e.g.:

Package: bitdefender-scanner-gui  
Filename: pool/non-free/b/bitdefender-scanner-gui/bitdefender-scanner-gui_1.0-3_amd64.deb  

See also Depends section, which would contain e.g.:

http://download.bitdefender.com/repos/deb/pool/non-free/b/bitdefender-scanner/bitdefender-scanner_7.6-3_amd64.deb

Download and install (with GDebi):

1. http://download.bitdefender.com/repos/deb/pool/non-free/b/bitdefender-scanner/bitdefender-scanner_7.6-3_amd64.deb
2. http://download.bitdefender.com/repos/deb/pool/non-free/b/bitdefender-common/bitdefender-common_3.1.2-1_amd64.deb

Once the Bitdefender is installed you can launch it with the following command:

/opt/BitDefender-scanner/bin/bdgui
