Malware-gen[Trj] and Pirrit-B[Adw] on my Mac

Malware-gen is not Mac malware, it's a generic detection for some kinds of Windows malware. This could be a false positive, or it could be detecting something attached to an e-mail message or the like. It's not a threat to you.

Pirrit is adware. If you're infected with that, Malwarebytes will remove it for you. If, after scanning with Malwarebytes, AVG is still detecting components of Pirrit, they are probably somewhere like in your Time Machine backups. In that case it's doing the right thing by not removing them - which would corrupt your backups - but it really ought to either not scan your backups in the first place, or give you information about why it's not removing files from your backups.

That has been happening all over the forums for about a week. Topics I'm in have repeatedly shown a response after mine which I cannot see until someone (or myself) adds another post. I've waited up to three days to finally see a response I knew was there, but remained invisible.

Try running Malwarebytes…

I wish I would have thought of Malwarebytes. 😎

Just curious, do you not see my Malwarebyte reply posted 3 hours before Thomas's?

I'm not sure it's the same case here but, at least now I understand the point of the "." posts. 😎

ASC is using a new set of Temporal rules.

Yup, that's exactly why we resort to those. The one and only purpose for them is to get previous posts to appear.
