1.) To block windowsmedia.com, ad it to your Norton and Earthlink blacklists. You can also add it to your HOSTS file.

2.) To get rid of the HP prompts, uninstall Backweb and look through Add/Remove Programs for any other HP update software listings. (Individual HP products have their own update checkers.)

3.) I don't know of any way to silence Norton but hopefully someone else does.
