I am not sure if my answer will still be relevant, since You posted Your question quite some time ago...
Nevertheless, I was wondering the same and came up with a solution I would like to share with others who would like to achieve the same:
(tested on Ubuntu-gnome 16.04 LTS, 4.4.0-62-generic)
1.) Enable eset-NOD32 scan via the command terminal (as already posted by OP)
Add a symbolic link in /bin to the default installation directory ( /opt/eset/esets/sbin/esets_scan) to allow for the execution of 'esets_scan' via the terminal command 'esets /DIRECTORY':
sudo ln -s /opt/eset/esets/sbin/esets_scan /bin/eset
2.) Configure nautilus-actions to enable threat-scanning via 'right-click'
[Note: for this to work You will have to use the nautilus file manager.]
Install the nautilus file manager configuration tool: nautilus-actions
sudo apt-get install nautilus-actions
Once installed, we open nautilus-actions and configure the 'Eset-ThreatScan' action:
- create a new action (click on the '+')
- go to the 'Action' tab. Under 'Nautilus Item' check following options:
- 'Display item in selection context menu'
- Context label: type in 'Eset-ThreatScan'
- 'Display item in the toolbar
- 'Use same label for icon in the toolbar'
- go to the 'Command' tab. Under 'Command' enter the following specifications
- Path: eset
- Parameters: %B
- Working directory: %d
- go to the 'Execution' tab. Under 'Execution mode' check the following:
Save the configuration by clicking on the menu: 'File'>'Save'.
Close nautilus actions and restart nautilus (you may need to pkill nautilus):
3.) Scan with eset via right-click
Simply 'right-click' on a selection (i.e. selected [multiple] folders or files) and select 'Nautilus Action actions'>'Eset - ThreatScan' in the in the up-popping 'right-click' menu.
The scan will be running silently in the background. Once the scan is finished, a pop-up will appear displaying the output-streams (including summary, errors and scan results, so the same as when run via the terminal).
You can close the pop-up by either clicking on 'OK', or pressing 'Alt'+'F4.
Hope this helps making Your life easier.
