Virus Signature Database constantly updating?

Recently upgraded from 4.1 to v5 So far, working like a charm. One minor annoyance however… multiple times throughout the day the Comodo task bar icon (lower right) pops an alert “The virus signature database is being updated…”, then a short time later “The virus signature database is up-to-date”. Is that supposed to update multiple times a day (like every hour) ??? Thx

Usually every 1/2 hour yes
