FWIW... if you restart the "Avast Business Console Client" and it's dependent "Avast Business Console Client Antivirus Service"... it seems to report correctly to the console. I haven't verified if this survives a reboot or anything but at least it gets things in the green again. On some of my devices, these same two services weren't starting up after at all, even after multiple reboots, but they would start manually and then things seem to operate correctly after that.
AVAST... guys... c'mon. I'm starting to cringe every time an update comes out... SERIOUSLY!!!
