This is the name of a virus among the all-time top detections recorded by this gateway. This historical view lets an admin distinguish a threat that was a big one-time event, high in the current-period table once but not here, from a threat that has been chronically detected over the gateway's entire uptime, pointing at a different remediation priority. For example, a worm name showing up here from an outbreak two years ago that still holds the all-time record despite no recent detections.
