pacify,
Waldo is correct, but I wish to elaborate a bit.
The initial scan is of the Boot sector and memory.
A full scan would be of the entire drive or drives you select.
You can have Avast run a memory scan each startup by loading the main interface (as Waldo has mentioned) and then right click anywhere on the Avast panel (or use the menu button in the upper left hand corner) to open up the settings screen. If you select (click) Settings, the screen that opens will allow you to check whether you want the Test to run at startup or not.
A full scan is just as easy.....load the main screen, select the drive or drives you want Avast to check, select any other removable drives such as external floppies or cd drives, and you can even select certain files......All from the rectangular main interface.
Start Avast and let it do its thing.
Great program. You will love it.
Good luck.
