All,
If this emupdate process was something that did not work at all, then I could see the multitude of complaints or suspicions might well be justified, at worst.
But that's not the case here.
What's the at best position? That avast! actively working on and refining and adjusting emupdate as we speak.
So, if there anomalies, as in FP detections with other security programs, why does anyone here expect avast! to fix other vendor's FP alerts or notifications? That's not how it works. In each case, each vendor is responsible for their detection database, and it is up to them to fix those detection issues when they come up. Not avast!
I can think of one reason, off the bat, why emupdate has been detected by other vendors: It is the random filename given to it by avast!; same criteria is also used as when avast! classifies a program as a PUP using the actual name of that program, as well as using other parameters. It is, in this case, likely is only the file name in this case as this file and process is digitally signed by avast!. I'm certain other vendors use exactly the same criteria to flag a digitally signed file. Who wouldn't?
Suspicion and paranoia can cause someone to walk away from a perfectly sound, valid, and legitimate program, and really, unless one is capable of actually analyzing programmer's code, that is all one has, a feeling of suspicion and that something is not right. That's all one is left with, and a hurried judgement not based on known facts can lead to potential disaster. Please stop.
Where's the proof!
Certainly if Vlk or someone else can step in and explain and reassure users that are uncertain and unsure about this, then it would go a long way to assuaging certain fears and doubts here. But, as in any discussion, such help will only come in if all are reasonable about whatever the discussion is about, and, those with doubts remaining, are willing to listen to the avast! team member, as it were. Otherwise, it is a waste of time to continue on with this.
I can assure you that team members are always busy, but do spare a little time now and then to clarify things here when it is needed. Otherwise, no, they won't.
