automatic scan at start up

[scattergun]

I just downloaded this application and it is set to automatically scan at start up, I want to modify this so that I can select when to scan, how do I change this scan set up?

If you are referring to the initial long boot-time scan before windows boots, you needn't worry as this is a one shot deal, it happens if you allow it after installation. It doesn't happen on boots after that unless you schedule it and then again it only applies for the next boot only.

If this is what you mean then this is how you can select it if required.

If you have XP, vista32bit or Win2k, you could enable a boot time scan. Right click the avast icon, select Start avast! Antivirus, a memory scan will take place followed by the opening of the Simple User Interface, Menu, 'Schedule boot-time scan...' Or see http://www.digitalred.com/avast-boot-time.php.

Are you using Windows XP/Vista?
If the scanning is coming all the times you boot, you can press F8 when starting Windows and select 'Last known good configuration' from the boot menu, the boot scan should not be started.
