My daughter passed on a tip that can alert you when you get a worm - which, I understand, attaches itself to the names in your address book. Add a fictitious email address to your address book. In the box where the first name is asked for type !000 and give the email address as [email protected] or whatever you like, I guess. This address will appear as the first address in your book - it does in mine. If a worm attacks your address book this email will be undeliverable and will be returned to you as such. You will then know that you have a worm. Lilian
