Norton AntiVirus wanted to block the newest verison 6.0 immediately after installation. Said it was detecting UDP traffic?

Today, 29 Feb every 10 -15 mins, Norton Antivirus detecting threat:  VBA:Downloader ART [Trj]

sorry for the late reaction on this issue, is it still happening?
We are not aware of any issues with our downloads, it’s probably a faulty detection on Norton’s side.
I suggest adding eM Client to exceptions in your antivirus to avoid being blocked from new updates.
