Scanning before computer restarts

I actually bought avast! 4 Professional Edition because it does scanning before the computer actually restarts. After I just bought it it did scan the way I need it but now I can’t even find an option to do scanning while the computer is in stand by mode, while the Windows are shut down. Anybody knows how to do it?

I think you mean “Boot Time Scan”

Scheduling the Boot Time Scan

  1. Click on the Menu button.

  2. Choose Schedule Boot Time Scan.

  3. Doing so displays a dialog allowing you to schedule virus scanning.
    Check Archives, if you want scan all the archives.
    Specify whether all the disks or just a specific folder should be scanned.
    Select Advanced options for scheduling details.
    Select how to automatically process infected files.
    Choose how to automatically process infected system files.

  4. Click the Schedule button to confirm the settings.

And after that, a boot scan will start, next time you reboot your computer.

The boot-time scanner (present in the Home version as well, btw) is performed when Windows start (i.e. then the computer is restarted, or powered on) - not when it wakes up from suspend or stand-by.

In the Professional version you can set the option to shutdown the computer after the scanning.
