Saying Fabian can be blunt at times is an understatement haha. He cracks me up at times with some of his posts.The topic gets muddied because people will say "Emsisoft uses heuristics." You have to qualify what they mean by "Emsisoft uses heuristics."
Emsisoft employs Bitdefender signatures - and the Bitdefender signatures utilize heuristics - but no part of the Emsisoft products proper use heuristics. At least that is how I have understood Fabian's comments about the products over the years. Now whether or not any of that has changed over the years... I don't know. Products can change, but from what I can tell, I don't think Fabian is a fan of heuristics - among a lot of other things.
Yeah I hear you. I don't want to start posting parts of the conversation since he was talking to me in confidence , but he said that it is built into the BD engine like you said and is utilized in real time analysis and that it's actually used quite heavily. And at times when the the analysis result isn't conclusive enough, the scanner and File guard query AMNet to verify it's not a FP.
