Re: computer with rootkit?

Clearly you don't have any experience with rootkits. If one were to get loaded from boot (bootkit) to initialize a 
driver or hook a driver, once the kernel SSDT gets modified your process list becomes inaccurate. You cannot perform 
*ANY* rootkit removal on an active system or your changes will be nullified by monitoring hooks.

You need an offline environment like the Hirens boot CD to load portable envoronment. Not only wipe the mbr but check 
loaded drivers at each runlevel then check local user and global registry startup points. Also a system file check to 
verify/replace modified system files. Then, and only then, you can even run your malware finders such as combofix, 
malwarebytes antimalware, and spybot s&d.

Repairing a rootkit infection is not that difficult. I've been reverse engineering them for years. Those who have 
suggested a reinstall should be ashamed.

There are a few things that you could try...

Use tools like process hacker, what's running, capture bat and regshot ...
Process explorer and process monitor can tell you what path and device
files are being used. Also look at the

(HKLM\currentversion\microsoft\windows\software\run) key in the registry
... most malicious program want to stay resident after a reboot... You can
use a tool called autoruns at well.

It looks like you may have a Kernel mode root kit. There is only so far
that those tools will take you .. To complete your process you are going
to have to dump the executable to a unaffected machine and perform more
behavioral analysis follow by code and memory forensics.

Hope that helps
