What Are the .### Files in my Win10 Users/ME/AppData/Roaming/.# Folder?

I have the following files in my Users/ME/AppData/Roaming/.# folder:

MBX@3EA4@4801A18.### 2KB 2/8/2018 5:45AM
MBX@3EA4@4801A28.### 2KB 2/8/2018 5:45AM

Norton scan reports Safe on these files, and there is no entry in my Registry for them. Virustotal.com reports 2 red instances for each of these files, one in CrowdStrike Falcon (ML) and one in Cylance.

There is nothing in Quarantine.

I am worried about these files. What are they?

I deleted the .# folder and its contents 2 days ago and it has not returned. I’ll check my \roaming folder every few days and if, after a couple of weeks, will mark this thread as a “solution”.

Thanks

Let us know your progress.  

Maybe, post on https://www.tenforums.com/  or https://www.bleepingcomputer.com/forums/

and FWIW ~ I think VirusTotal detection 1 or 2 out of 66 or 67 strongly suggests false/positives.

Here are 5 of the VirusTotal links:

And yes, I do have a folder that is named ".#" and that contains ".###" files.

Thank you for your help!

Norton malware forum site?

I think you meant to write that the file extension “MBX” is created by Outlook Express. I’ve run the Windows Update and it tells me that I am up to date (the last update was either earlier this week or late last week).

MBX is an email file format created by Microsoft Outlook Express.

maybe, run LiveUpdate until no updates + machine Restart (not Shut down) and run Full Scan with Norton Security.
