If you have a decent one it will scan new files on your computer automatically. If you don't, Shareaza allows you to use your scanners command line to scan new files automatically once they have finished downloading. Plz have a look at the Shareaza settings and see the manual of your anti virus application for more information on how to use it via command line.
