This function isn't available in the free Home version, there is a work around though.
HOWTO: Scheduled Automatic Scans avast! Home Version!The major disadvantage with the task scheduler trick of using ashquick.exe is, it will scan every file of the hdd, partition, folder or file that you set it to scan; even those files not considered a potential threat, this can take a long time.
The Pro version gives a lot more flexibility and the scan would follow the settings and exclusions, etc. of the regular scan.
I prefer to do a manual scan with my regular weekly maintenance tasks.
I feel that with the protection in depth of avast with its various resident scanners (web shield, email scanner, etc.) backed up by the Standard Shield the old style on-demand scheduling of a scan is lessened.
