Can virus database updates four times each day?
Updated twice each morning and afternoon?
as u experienced that behavior, yes it can…
or didn’t i get ur question?
avast free version automatically updates each 4 hours.
avast pro version automatically updates each 1 hour.
That should read, the “avast free version automatically checks for updates each 4 hours.” This can be reduced in the UI settings to every two hours (120 minutes), so if there is an update available it will be downloaded.
You’re right David. My bad.
