avast is a resident scanner so the need for regular on-demand scan is much reduced.
Currently only the Pro version has scheduling, the free Home version doesn't. So what version are you trying ?
Version 5.0 in beta right now, when released will have scheduling in the free version also, but for now, not.
- In the Home version you can check the option "Don't show this window again" when the first virus warning appears, select the "No action" button. This way, no action will be taken and you will given the results at the end of the scan (and you can perform actions from there).
Over time this will become less of an issue, as the resident, on-access scanners are designed to intercept infection before it gets into your system. - There was one suggestion to place something like the eicar virus test file at the start of the first drive to be scanned in a file like ~a-eicar.com that should soon be detected and you can do the option "Don't show this window again" when the first virus warning appears, select the "No action" button. So you should have a list of files waiting your action.

The work around wouldn't allow you to schedule it as you have to be there for the first detection, though there is another work around.

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.
It is possible to add certain folders to the exclusions list for say your media files, etc. Care should be taken with the paths you want to exclude as this could leave you vulnerable if that folder got infected as it wouldn't be scanned by the on-demand scanner as you have excluded it. However, should you access any infected file in a Folder in the Program Settings, Exclusions, the on-access scanner (Standard Shield) should detect it provided you haven't put the exclusions in there.
The Pro version gives a lot more flexibility and the scan would follow the settings and exclusions, etc. of the regular scan.
With the different levels of protection (Web Shield, Internet Mail, P2P and Instant Messaging) and the fall back of the Standard Shield, I find the need for daily scheduled scans lessened. I prefer to do a manual scan with my regular weekly maintenance tasks.
