I have a 2TB My Book external drive.
It seems to be creating random folders on its own and i do not know why.
The names of the folders make no sense and I cannot delete them.
Name examples: 4f562c98e0da49830ec7b66e6011b0
Most of them are empty but some have this file in them:
MpMiniSigStub.exe or mrtstub.exe
Anyone know what this is and how can I stop it?
.exe files being automatically created is a serious sign of virus infection. I would recommend scanning your device (And your entire system) with your an anti-virus application, and proceed to fully clean the unit by using the write zeros (Full erase) option of Western Digital Data LifeGuard Diagnostics for Windows. This will perform a low-level format sector-by-sector.
