Hello JohnOzuk
Please submit again to Norton for false positive. They reply within 24 hours with a file number. If you get the file number from Norton, please post it in here. Also, if you have already emailed it to Norton, please check your Spam Detector. Often emails like this end up in Spam Detectors. If you get a file number from Symantec/Norton, then I can check it out with Norton.

Thanks.
Still not a peep out of Norton. Am I being too anxious? I am not 100 percent sure it was sent.
Hope submitted, web page never came back with a success message
@JohnOzuk: What are the most recent changes you made to your PC? E.G., downloading/installing some software (Free YouTube Downloader, e.g.)?
Try un-quarantining that dll file; share us with an img of the Properties tab. Please do no miss the Digital Signatures part if it is available there.

PS: Heur.AdvML.x: Heuristic Adware v(?) Malware (Down)Loader?

How to report false positives ...will reply to you.
Do you have Norton Heuristic Protection at Automatic. If you turn Heuristic Protection Off and can reproduce event. Norton may report e.g., WS.Reputation.1
Thanks again, did find a send to Norton option in quarantine, which I did. This is only hash I could find. Hope Norton replies at some point.

step thru form and see options e.g., https://submit.symantec.com/false_positive/standard/
Heuristic detection as you know is an artificial intelligence guess.
Thanks
So I will need to un-quarantine to send to them?
