Correct.

In PC-Cillin: Quarantine / Restore.

Not quite correct. I had a virus (obviously in an attachment) that was
not in the list of viruses that PCC knew when it arrived. It was some
macro virus in a Word document that was attached to an email; as it
never did any harm it is likely I never opened that Word documents. I
keep attachments in the message body.

Once PCC was updated and I tried to open that folder, the real-time
scanner quarantined the whole .tbb file. Proving that PCC does indeed
scan MIME encoded message attachmenbts stored in the message body.

Certainly correct. But this has nothing to do with plug-ins or not,
has it?

And this is also true: PCC quarantined the whole .tbb file, as it only
knows to quarantine files, not messages within a file. A plug-in would
have quarantined only that message (maybe even only that attachment?)
saving me the trouble of sifting through a couple of hundred messages
to find the one with the virus.
