Minidump folder locked

I just had a crash on my Desktop computer and planning to analyze the dumps but to my surprise the minidump folder is locked and the minidump files inside it cannot be copied to a different folder. I can go into the Security permissions of each file and add my administrator account there and fix the copy problem but my concern here is why was it suddenly locked?

I have other computers here in my environment and their minidump folder are not locked at all. So what causes it to be locked? We all have the same settings in our antivirus program.

Please help. Thanks.

Check for malware/viruses.

To start, run your anti-virus scans.
Download and run Malware Bytes Anti Malware free.

I already did that and no results. I don't think there is a malware though. I googled about this and I saw a harmful of hits that had the same problem and it was not connected to having an infected computer.

Any more ideas?

Will try that. But one question, will deleting the whole minidump folder be ok? Will Windows just recreate a new folder when there is a minidump to write?

Yes, a new minidump folder will be created.

With the proper permissions?

A new folder was created without a lock icon when I deleted the original one but after a few days it eventually had that lock icon again and I cannot copy the minidump files inside again. It seems that the files does not copy the permissions of their parent (Minidump) folder. Why is that?
