About a week ago Firefox froze up and couldn't display any pages on the internet. I ran some programs and could not find anything until I ran combofix (I know, I know!) and it said it found rootkit activity and would reset the computer. After the computer reset it would do a complete scan and find nothing. Out of curiosity I ran the scan again and it found rootkit activity and after it reset it found nothing. Just to be safe I flashed the bios, put in the a windows sp3 bootdisk did a fixmbr, reformatted the hard drive, and reinstalled windows. After getting everything back up and running I did a combofix scan and found nothing. I did nothing else to the system except allow windows update to run. The next day I did a combofix scan and it detected rootkit activity. I've gone through these steps several times now and keep getting the same thing. I've done scans with many different rootkit scanners and they found nothing until I tried rootrepeal and found this in part of the log:

Name: atapi.sys
Image Path: atapi.sys
Address: 0xB9F31000 Size: 96512 File Visible: - Signed: -
Status: -

Name: atapi.sys
Image Path: atapi.sys
Address: 0xB9F31000 Size: 96512 File Visible: - Signed: -
Status: Hidden from the Windows API!

So Combofix and Rootrepeal keep finding something, where no other malware scanners are. I scanned atapi.sys on the virustotal website and found nothing. My system is not really having any strange behavior anymore, but was wondering if there is still some kind of infection on it. Here are the DDS and Gmer logs/attachments:

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 your topic an do their best to resolve your issues.

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:

How to create a GMER log


Thanks.
