I have seen that pop up before but it seems to have stopped. I do get notices in the Notifications fly out (Windows 10 Home) that NOD32 requires my attention and to click on the notice for additional information. Clicking on the notification does nothing. Looking in the NOD32 window does not have any indication or notice that any action is required. Tech support suggested a reinstall of NOD32 which I did but still got an occasional notice. Yesterday I did a clean install of Windows 10 and got everything set up and running. This morning I did a smart scan of all the drives and everything was clean. Shortly after the scan there was a notice in the notification fly out that NOD32 required my attention but as usual nothing to indicate what, if any, problem requiring action existed. ESET is shown as running in the services menu. Everything appears to be operating properly, is up to date, and without issues so nothing seems to be broken. The attention required notice is a bit disconcerting leading one to believe there is a problem but I guess it is nothing more than an annoyance until the day NOD32 really does require my attention and I don't bother to check it out.
