trz***.tmp what are them and how to rid of them?

I have found several trz***.tmp file on my computer, but I can't delete them. Every time I try, I got access denied. But I'm already logged in as admin. Those files showed up after I started using Teracopy. And they are in the destination folders that I used Teracopy to move files. Anyone knows what they are and how I can get rid of them?

Thanks,

These sound like temporary files created during the copy process. Normally, access is denied if they are still in use. Is Teracopy still open? try closing it and see if they dissapear. You could also try a reboot, and then delete them if you don't require them any longer.

Let us know how it goes.

TFC seems only work for the system drive. As the files in question are not on the system drive, TFC didn't do anything to them. But ran it anyways.
As of Malwarebytes', keep getting run time error '6': overflow after 10-15 seconds. Tried several time without success, even disabled all my AV, Firewall, etc. Anyway, I ran a full scan with MSE2 and found no threat. I also have CIS and Avast (am I being paranoid?) running all time. So, can I assume those file are not harmful?
