Windows 7: Verifier shows drivers from unknown provider

Verifier shows drivers from unknown provider

The driver verifier program, Verifier.exe, shows 4 drivers from "unknown provider".

The Drivers tab of Autoruns.exe does not show these.

Neither PowerShell nor Windows Explorer finds them and yes, I even specifically looked in Windows\system32\drivers.

The quick Malware Bytes scan and the quick MSE scan found nothing.

Here is a snip from the driver listing shown by Verifier (sorted so that the unknowns show up first).

The ones beginning with dump are typical in a crash scenario. The top one is the default sata driver supplied by windows, don't know why it's showing as unknown provider.
It does happen though...
They are usually emergency drivers just for the purpose of writing a dump file.

The last one I am unaware of, being stuck on my laptop I don't have immediate access to my usual resources though.

Notice however that those driver names shown are not the ones typically associated with dumps. Just I second and I'll do a search with PowerShell and show you what I mean.

I can't point you to the driver reference page on it because...like I said I'm on my laptop and don't even have that stuff on this thing.

It's something I'm quite used to seeing in just about every minidump file I've ever run a lm t n command on though.
