Have to join in when I saw this thread. Same problem.
Window 7 64, Eset was working a few weeks ago, without this flickering of asking about a connection. Can't even read it is so fast. Interactive mode (firewall).
Happens, with Mail Washer pro 6.5.4 (old version) and "Internet Download Manager"
I uninstalled, went back to my other Firewall.
I was beginning to like Eset Internet security.
No support ticket, it was like a circus just to join this forum.
Wont reinstall until this is fixed.
Major Problem for me!
