I don't have the Software Updater module installed, mchain.
The interesting thing is that now since I've been on my backup computer the last 3 days I believe it is ... I have not encountered the mysterious vague message.
But, interesting that you should mention Software Updater. Now that I'm on THIS computer (backup), now I've been seeing a "SoftwareUpdate" process in my Task Bar. It can't be avast since as I mentioned, I don't have that module installed. It's possible that it is my Epson printer software. I could have sworn I told it (Software Updater) to stay out of the equation. But, software doesn't alway listen.
Anyway, for now I guess I'll put this issue on the backburner since for the meantime, I'll have to be on my backup computer and not on my main computer, the one that was exhibiting the issue.
