does avast pro scan automatically?

Avast Free Antivirus / Premium Security
1

if I want a periodic scan to take place, do I have to configure a schedule for it, or does avast internet security 2015 do some type of periodic scanning on its own? Like after updating the virus defs, does it do a quick scan or something?

Well, basically it scans all the time, it’s an on access scanner.
Still, you can schedule your own scans, if needed.

@ shmu26
With a resident on-access antivirus like avast, the need for frequent on-demand scans is much depreciated. For the most part the on-demand scan is going to be scanning files that would be otherwise be dormant or inert. If they were active files then the on-access file system shield would be scanning them before being created, modified, opened or executed.

I used to have avast set to do a scheduled weekly Quick scan, set at a time and day that I know the computer will be on. But I have ceased this practice for some time now, based in the above.
