No Avast Mac Virus Definition Updates Since August 31

Normally my Avast Mac Security install receives virus definition updates daily. There haven’t been any since August 31. I’ve checked multiple different Macs–same story with all of them. Wondering why.

A few minutes later: Oops–never mind. Just tried a manual update, and for the first time since August 31 one was available. Still, it was unusual that there weren’t any updates between then and now.
