I had the same thing happen Jill. While I was out of town for a weeknd, so I know it wasn't from me to me. It's not an address book problem. The virus we are most likely noticing picks addresses out of the cache, so if someone reads a BB it will just scoop up all of those.

For example, someone we don't know, who doesn't post here, comes to look. They have the virus. It picks the names, at random from cache and we all get the dang attached files.

I got two more tonight, but no problem, Netscape (and Eudora) just see a blank message, and I can delete the whole mess.
