I suddenly have exactly the same alarming Personal Firewall, Network Attack Protection and Botnet protection problem as the original poster on this thread, and also only have the "Disable Permanently" drop-down option against each item.
I also notice that the Firewall "Learning Mode Settings" section (and sub-sections) is completely greyed out. I don't know if this is connected to the main problem.
However, the "Home" page of my ESET GUI says everything is OK.
Finally, I find that in Advance Setup\User interface Elements\Application Statuses, the "Personal Firewall dropdown is telling me that Firewall & Botnet Protection are paused AND non functional!
What on earth is happening here? Have I been invaded and my settings changed? I'd taken off the settings password protection function a while ago because it was interrupting so much (for my own good, I know. Stupid me!
Screengrabs attached.
