I've changed no settings. But all of a sudden Norton Internet Security, which I've used for years, faithfully renewing, is letting through an inordinate amount of spam to my Inbox from e-mail addresses/web sites I've never heard of. The common characteristic among each and every one is that none of them have a Subject field filled out (the Subject is consistently blank). Don't know why they're getting past Norton all of a sudden like this. Indeed, is there a way I can block any e-mail that does not have a Subject? Thanks for anyone's info or advice on either of these issues.
