I just purchased a 2-year contract for the ESET Internet Security software for use on my (3) unbuntu 20.04 systems, but have had difficulty in the installation. First I had to find the web page where I could download the installation executable by searching the website (found it at: https://www.eset.com/us/home/antivirus-linux/download/) whereas download links were provided directly from the application for Windows, Mac and Android - not sure why Linux wasn't included there. After running the executable and restarting the system, it prompts for my username and password for updating the virus signature database and it gives me an error on my username/password. I tried using both my email address and the username that was specified in the email I received after purchasing it, and the password I used was what I used to register with (which I know is valid for logging into my account online), so I'm not sure what I should be using for these values. How do I resolve this?
