Nope, still there.

Might have to stop and restart the Mail Shield component in Avast; i.e.,
disable and renable that shield. I got rid of Avast's Mail Shield a
long time ago. When I investigated, I found it is superfluous: add no
more protection than the on-demand scanner which it uses, anyway. It
can cause timeouts between client and server, too, which generates
errors. Uninstalling the Mail Shield component from Avast would
definitely get rid of their spammy appendage to your e-mails and
newsgroups.

Could be Matitico only disabled the spammy fake signature on e-mails.
There could be a separate setting for messages sent to newsgroups.
E-mail and newsgroups are not the same thing.
