ThinkPad + ComboFix = rootkit?

We had a customer ThinkPad R61i that came to us pretty badly infected. During the course of checking it out, we saw a number of disk errors in the system log, and ran some HDD diags, and the decision was made to replace the HDD. We backed up his data and ordered a replacement drive.

We replaced it, reinstalled XP Pro SP3, restored the users files, and, naturally, the infection came back. So we rebuilt it again, scanned the hell outta the backed up files (finding some stuff in unnecessary places, which we removed, but nothing that looked serious), put them back and scanned it again - and ComboFix again tells us there's rootkit activity. Neat.

So this time, I removed the new drive from the Thinkpad, used HardDriveEraser to write zeros to the drive, then did two DoD wipes on it, and replaced the drive. Then we rebuilt it again (XP SP3) and installed drivers (without replacing any user data). Then ran ComboFix again, and...

"ComboFix has detected the presence of rootkit activity and needs to reboot the machine"

Help? WTF? We do five or ten malware removals in our shop every week and this is totally a new thing to us.

So I let ComboFix run all the way through, it reboots and shows me this log:

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Upon completing the steps below another staff member will review and take the steps necessary with you to get your machine back in working order clean and free of malware.

If you have already posted a DDS log, please do so again, as your situation may have changed.
Use the 'Add Reply' and add the new log to this thread.

Thanks and again sorry for the delay.

We need to see some information about what is happening in your machine. Please perform the following scan:
  • Download DDS by sUBs from one of the following links. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explaination about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE

We also need a new log from the GMER anti-rootkit scanner. Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice

Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:
