For the sake of anyone doing searches for a solution to making the ESET NOD32 show the Unity panel icon in more recent distros such as Ubuntu 14.04, there are two straightforward solutions that I have found:
1. In Terminal run the following command (after installing ESET NOD32) - Reference hxxp://www.av-compar...nux_2015_en.pdf
sudo apt-get install libappindicator1
OR
2. For those that prefer an option that fits in with the Unity Theme one can add a new AppIndicator called Indicator Systemtray Unity which adds a system tray to the Unity panel. A good howto can be found here hxxp://www.webupd8.o...for-ubuntu.html
Certainly hope that the ESET NOD32 team keep their Linux version maintained, as it is certainly one of the best options when it comes to Linux antivirus programs.
