Since using Norton Internet security, Ad-Aware and getting a new YaHoo address, I have been lucky too. I noticed that some of the spam was based on sites I visited, but never entered info on. They just saw my browsing habits. The worst was last summer when I signed up for a Hotmail account and THE DAY I did, I got 20 spams! NO BODY knew the address yet! :O I also don't post my email address online without swapping the @ for (at) (see my profile).
