Windows 10: What is this odd file?

I am running Windows 10 Pro which is fully updated. Recently I have noticed an odd file with the name of UpdateLock followed by a series of numbers and letters. The file is located in the Program Data folder, and is 0 Kilobytes in size. If I delete it, it re appears within an hour. I have scanned my computer with Malwarebytes, Microsoft Defender and have found no infections or malware to be present. If anyone knows what this is, I would be grateful for the information.

Identical File Finder

I don't think that step #3 is even needed. The probabiliy of two MD5 hashes from differing files colliding is what, 2^-128 ?
Even if your were hashing a million files the odds of a hash collision on differing files is astronomically small.

It could also happen because of network issue. I suggest you to try with different network connection and check if it helps.

 

User can't copy files from network share. Permission error.

Seems security essentials wasn't liking the file for the user for some odd reason. Thanks for your suggestions.
