I use Avast Premium Security on Win 10. Is there a setting for auto scans? I thought there used to be auto scan with Avast Pro.
What do you mean by Automatic ?
Avast is a resident on-access antivirus, so when a file is created, modified or run it is scanned (automatically, dependant on file type).
Or do you mean a scheduled on-demand scan ?
If so that function remains, but you need to open up the Scans Settings and set the schedule. Once set then it too is automatic.
