PFhex.PDF files being created 24/7

Report · Apr 12, 2016

Starting on Sunday, April 10, Acrobat files of 139,030 KB are being created every 4-5 minutes in the windows/temp directory. They are all of the same 1-page image of a file I haven't touched in several months. What gives?

The files are all named PF####.pdf, where #### is a seeming random hexadecimal number (letters A-F plus digits 0-9). They are being created in the C:/windows/temp folder.

Thanks for any help you can provide,

Jack

Do you have Distiller SERVER 7 or earlier? If not, what Acrobat product is installed?

Thanks, sorry for the late response. I have Acrobat Pro DC 2015 V 2015.010.20060.

Fortunately, I was able to identify the original file that was in full, or part, showing-up in each and every one of those rogue files. I scanned if for mal/virus, but it was clean. Then I changed the file extension from dot pdf to dot xyz and haven't had the problem since.
