I think they reappear after I run a program or do some action but have not been able to identify what actions are causing the files to regenerate.
Then try to identify the program that is creating them.
These files do no appear to be malicious and your jotti scan seems to confirm that. I am seeing a lot of users having the same files in various logs where they posted for assistance in regards to other issues. What I find in common is that all of them are using Nvidia graphics/drivers. What I have noticed in some of these logs, those files have the same date/timestamp as nvapps.xml and nvudisp.exe which are Nvidia related.
Some files are necessary for a program to perform properly and are recreated if they are deleted.
