Can I tell if my address book has been compromised?
I recently sent and received a series of emails to a colleague (I use Thunderbird, he accesses Verizon Mail online).
The gentleman claims that 'immediately' afterward he became deluged with spam mail.
He rarely uses that particular email address, I use mine constantly. No one else I correspond with has noted any change in behavior, just this guy. He is fairly security savvy - I doubt he would do the usual stupid things to invite spam.
The only thing that occurs to me is that something copied my address book (and only sent spam to him - huh?)
But that got me to thinking: would there be a way to tell if I was compromised in that way?
I run Avast! (free) and the Mail Sheild is on.
Thanks for any thoughts or ideas.
