Nothing to do with ClamAV, 'cuz it's a Mozilla/linux feature.
It's related to a Mozilla bug:
https://bugzilla.mozilla.org/show_bug.cgi?id=209501 ... They've been working
on it since 2003 ...
In one of my Trisquel PC's, on which I haven't yet started consolidating
emails, I found two emails with no subject, no headers, and no body but with
the 12/31/1969 date as the only information, associated with folders in which
the latest entries were both related to the changing of passwords, one for
this Trisquel forum and the other for my McAfee antivirus (used on the WinXP
OS on my laptop).
Evidently, folks in the linux community have been using linux's zero-time
glitch to make/modify admin passwords with some sort of trickery:

Search on "password 12/31/1969" and you'll see how ubiquitous this problem
is.
Finding where this mysterious phantom email resides is another matter having
nothing to do with malware.
Call it dateware, if you will.
