What could be the explanation for this one?

Naturally, it would leave me to suspect external malicious influence ("a person" (using "a program")). But perhaps I am too quick to conclude.
Your av software might "lock" the data if it's scanning it (although not necessarily), or if it's quarantined some of those files (although that usually happens in a different directory).

The data, whatever it was, I'm assuming was opened with a program... sometimes, various programs don't let you delete, for example, the last file you opened in them (the most recent example I can think of is a savegame from a heroes game; fresh reboot didn't help, the game was obviously not running, etc, etc. Trying to delete the savegame resulted in a popup saying that it's in use by an application. Not a big deal for me at the time, could have booted in linux and deleted it at any point, but it's worth mentioning the issue, I reckon). Mind you, this is faulty behaviour.

So yes, there could be valid reasons and explanations. Did you scan your system ?
