Sorry your right that is the resident, on-access scanner task on boot.
The Test memory on application start refers to the ‘Start avast! Antivirus’ selection which starts the Simple User Interface, SUI (on-demand scan), first it scans memory to ensure that is clean before starting the on-demand scan, if a virus is found in memory it should offer a boot-time scan.
Try unchecking it and right click the avast icon, select Start avast! Antivirus, the memory scan will pop-up but no scan wil be done before the SUI is displayed.
