MpKs????????? Files

Running Windows 7 Ultimate with Bitlocker, patched to date (except I am still using IE 8), on a Gateway CX2724.  Use MS Firewall and MS Security Essentials, which is also kept updated.


In Device Manager:

All my devices that normally show in Device Manager are good, but among my hidden devices I have under Non-Plug and Play Drivers, 67 instances showing a yellow exclamation mark, all named of the form MpKsI????????, all with a Code 24.  I found a reference on another forum suggesting these are created by MS Security Essentials, and implying that they can be removed.  Is this correct?

I also have under Non-Plug and Play Drivers one (hidden) driver of the same form of name that is said to be working correctly, and it's driver file is in "\??\c:\Program Data\ Microsoft\Microsoft Antimalware\Definitions Updates\..." (cannot see entire path, nor name).  Can it also be removed?

And also under Non-Plug and Play Drivers I have 135 other hidden drivers of the same form of name that are "ghosted" (i.e. non-present).  Can they be removed?


Question Info

There was an MSE bug some time ago that was corrected.

You can safely delete/uninstall the 67 instances and the 135 ghosted instances.

Leave the one that is working correctly alone.  There will always be one. It is a part of the process.

The bug was that MSE did not delete the old ones.
