Thank you for your response regarding this matter. I figured out that Ubuntu is now running systemd and that I had to 1)create eset.service file, 2)sudo systemctl start eset, and 3)sudo systemctl enable eset ESET now launches when I boot into Ubuntu. However, ESET will not not accept any trial license or update virus signature base. I keep getting a popup that says Invalid username or password. Any advice would help. Thanks.
