The Klez virus works by spoofing addresses. It looks at the address book
on the infected computer and randomly picks two addresses. It uses one as
the To address and one as the From address.

In other words, if you get email containing the Klez virus from someone,
it doesn't mean they have the Klez virus, it just means that both you and
the person the email seems to come from are both in the address book of
the computer that *does* have the Klez virus.
