Hello,
I see there's been some talking about this Win32:Hupigon-ONX [Trj] subject so I rather put my question here, than make a new topic.
I recently faced this very same infection alert with doing full virus scan via Avast. It reports the file being highly infected with this very specific kind of Trojan. But is this a real threat or a false alarm since the file is being in Avast's folders. File location is C:/ProgramData/AVAST Software/Avast/ng/NGBase/Snapshots and full filename is snapshot_{1d35d8b8-b359-11e3-b1fd-806e6f6e6963}.dat - this dat file is 1,7 GB.
I have tried to do what avast suggests after scanning, so repair automatically and/or deleting the file but nothing happens. Is it safe and should I manually remove this file, if it isn't a false report from avast? Malwave scan doesnt give any alarms about infected files.
