I have a workstation that was recently infected with Mal/Krap-B, Troj/Spyurs-Gen & Mal/Hiloti-D - these are all identified by Sophos.

I was able to remove all but the Mal/Krap-B located in C:\Windows\System32\Drivers\STMIU.SYS using Sophos antivirus command line SAV32CLI tool. This file is unable to be opened and is skipped over.

I've contacted Sophos support and they just ask me to send a sample. When I try sending a sample I get an error that this file is empty or nonexistant.

I've tried using Malwarebytes - file assasin and that didn't work either. I've used RootRevealer and it finds the file and it can not remove it.

I'm now at the point of wiping the OS (which is XP sp3) and starting over but that is kind of like admitting defeat!

I have even tried a simple delete command in Safe Mode with Command Promt (del C:\windows\sytem32\drivers\stmiu.sys) and I get the message that the hardware attached to this is not responding.

I feel like I'm missing something simple here but I'm not quite sure what it is.
