Unknown File Verified - Should I be concerned?

Thanks for your help but I better leave this alone. I ran those scripts like you said and I see a number of lines with "Failed to get bridge device" in them. I'm afraid I'll really mess things up. Thanks again for your help.

See if there is anything here that looks applicable to your situation—

I have an M1 Mac mini running Monterey.

A few times a month I see a file flash across the screen but it gets verified before I can see what it is. It may be different files being verified but like I said I can't read them. Today a file paused a few seconds so I can read it. It had no real file name, just a few characters, mostly things like &*# etc.

Being that Apple was verifying it and it was allowed to download to my computer, can I assume that this file is safe? It's just odd that there's no real filename.

After it downloaded, I ran Malwarebytes and the scan came up clean.

That is not very specific, vague at best— "mostly things like &*# etc.....(?)"

Downloaded? How do you know it was a download?

Under what circumstances is this happening, from what application?

Try turning off Automatic updates and test over time... you should still get update notifications without issue.
