ESET or EMET? I think EMET, which is "Enhanced Mitigation Experience Toolkit" when I searched (although I only see a reference to V 3.0).
In any case, you are asking in the wrong forum. This forum is for questions about the forums themselves. I believe you should ask in a Microsoft Answers/Community forum, perhaps dedicated to security issues. I cannot move this question to an Answers forum,
but I found some similar questions in this forum:

You will need to post your question there.
