Avast Internet Security Scheduling Scan?

I have WIN7 and Avast Internet Security paid version. How can I setup a scan schedule? I had it before on the free Avast version but I can’t see any way to enable it on the paid Internet Security version. Thanks, Bob.

Err, go to Scans > select scan type and schedule.

On the GUI > Tools> there is a “?” that takes you to the HELP file, all the controls and settings available are detailed there.
