Large numbers of random false positives (Trojan.Gen.NPE.2)
Over the last few days, Norton Security version 18.104.22.168 running on a number of Windows 10 PCs in my home has started throwing large numbers of false positives all for the same catchall definition: Trojan.Gen.NPE.2. The one thing the files subject to these false positives all have in common is that they're significant Windows files like dcdiag.exe or wevtsvc.exe.
What clued me in to this being a rash of false positives was that it impacted machines that are heavily used AND two brand new machines that'd literally been out of the box less than an hour and only connected to a separate, isolated network with an aggressively filtered VPN and never so much as had a web browser run on them before. What removed all doubt was that after I'd inspected the files, determined they were clean, and restored them without adding exceptions, the next full system scan I ran declared them clean... but then flagged a completely different collection of essential executables as Trojan.Gen.NPE.2. Lather, rinse, repeat... I've been at this for three days with no end in sight with these false detections periodically breaking various Windows functions.
I've submitted all the files to Norton, and each new definition update cheerfully exonerates the last batch and flags an entirely new set of files as Trojan.Gen.NPE.2.
Is anyone else out there having this issue, and is there a way to contact Symantec and have them initiate some kind of review to address the problems with their Trojan.Gen.NPE.2 definition so it stops quarantining clean Windows files?
