I was looking for root kits following these instructions http://computersight.com/software/how-to-manually-remove-rootkit/ and saw this in my boot log:

Loaded driver \SystemRoot\System32\Drivers\awhk9fmc.SYS

I tried to search for that filename in Google but there was absolutely nothing found. I tried to look at the file on the disk but could not find it. Nearly every other file is there. I even tried to boot in Windows 98 and mount the NTFS and see the file, but it still wasn't there. I ran a full scan with Microsoft Security Essentials but it found nothing. When I rebooted, I saw this line instead:

Loaded driver \SystemRoot\System32\Drivers\a6n163gl.SYS

1. How can I remove this?
2. How can I find out what it does?
3. How can I find out when it was put in?
4. How can I find out who wrote it?

Here is my full boot log:
