timing scans

is there a way to set the computer to run scans when no one is on it like setting it up to run at 2.00am?
thanks paul

If you mean like a scheduler then the pro version of Avast allows this, if you currently have the pro version this function is found under the enhanced user interface

Scheduling is only available in Professional version.

To schedule automatic scans in Home version: http://forum.avast.com/index.php?board=2;action=display;threadid=3796
