Add the following to your .htaccess file located in /home/username/www/

Options -Indexes

Note 1: "Options -Indexes" prevents browsing of directories that have no default index document. (Most people don't like visitors crawling around in image file directories, for example).

Note 2: Worms will still make entries in the access logs, but spotting real errors is easier when the error log is clean from "worm droppings".
