Thank you for the answer.
Meanwhile, somebody should hastily update the 'help' information. That would have saved me time waiting for support to reply with an ambiguous answer as to what it (question mark and time of discovery) meant. I could of course just have submitted an infection report.......though that would obviously still have left me at the same, diminished, level of confidence with regard to eset smart.
I can guess at what you mean by "..reputation cannot be obviously determined". It is also a bit ambiguous, IMO.
Yes, it is hard (impossible) for eset to ascertain whether MS is 'good' or 'bad' with their OS and to analyse all their code. Though I thought that you (eset) had some insight that would warrant better than just an undocumented question mark.
Thanks.
