I have an external Hard Drive and from time to time a random folder named something like 2eca741dd6d1f17e12bd34da6e546f appears. I delete it and some days/weeks later it appears again.
The folder contains a file named MpMiniSigStub.exe
What is it?
When I try to delete it, I have to delete it as an administrator. Also, the name isn't the same every time.

Windows updates creates folders with these kinds of names and does so on the volume with the largest percentage of space available.
So if you have a computer with two drives:
1) Internal HDD, say 80GiB, 40GiB full (50%)
2) and an external drive, say 10GiB with 2GiB filled ( 20% full ),
Then it will create these folders on the external drive.
