Windows 10: software generates pgm files that are occasionally quarantined

Hello.


I have an imaging system that generates pgm files portable gray map. Very infrequently 1 in 10000 these files are quarantined by Windows. But, when they are quarantined it causes a processing disruption that is a headache to fix.


I have been researching the issue and I think the best solution is to save the image files in a compressed format png or similar. Before going down this path, I want to get advice from someone with more experience.


I submitted one of the quarantined files to virustotal.com, and it was only flagged by Microsoft.





I feel like the issue is that by coincidence some part of the binary in the pgm file resembles the binary in a known exploit what are the odds of that??.


But why is the file only flagged by Microsoft? Is there a way to avoid this issue and maintain the pgm format e.g., some how indicate all images coming from the camera are safe? Will moving to a different file format for the images resolve this issue for good?


Thanks for your help!

Generating a .txt based file list in Windows 7

I want to be able to generate a .txt file that lists all the files and folders in a specific folder on my PC, but don't know the name of any programs that do that. Searched on google a bit and came up with this guide, but it's for XP and I can't seem to find some of the folder options to modify the .bat file. Any suggestions? Thanks

EDIT: The .bat file will do what I want if it is in the folder I want to do it in, but the option I want to add is having the right click option that it shows.

 

Occasionally "Microsoft print to pdf" creates empty files

Have already done all of the steps suggested in that link.
The problem only happens occasionally; maybe two or three times a day.
Happening on several PC's, the only way to catch it before it goes to customers is the size of the file created.
If it is 0 or 1kb, it's a blank document.
Microsoft Print to pdf was working fine until about two weeks ago.
Thank You
