Back some time ago I tried to use ESET v4.0.66 on my Ubuntu box (I think I was running v11.10 at the time) and had some minor issues between it and my Logitech wireless mouse and keyboard (mk550). I decided to uninstall at that point in time. I see that you now have v4.0.77 and thought I would give it another try. But I cannot get a trial activation key. How could I get this key? Thanks for your help.
