My Dell home computer with Windows XP was infected with a rootkit a few months ago. After months of trying to unsuccessfully remove it with multiple programs, I performed a full reformat of the hard drive this weekend which included removing all three existing partitions. After installing the drivers and Windows updates including Service Pack 3, I downloaded the latest version of Combo Fix and ran it to verify the rootkit was removed. Within a minute or two a popup came on the screen saying "ComboFix has detected the presence of rootkit activity and needs to reboot the machine". This popup was in Windows format (the desktop view was still on and the popup was the typical gray box) with an "OK" box. So after I hit "OK", the machine locked up and forced me to manually shut it down after a long period of waiting. After booting up, ComboFix started it's scan beginning with Stage 1. The ComboFix log does not appear to show rootkit activity.

I have also run ComboFix in Safe Mode and have not had this popup. But it always happens in normal mode including the machine locking up.

So what I'm trying to determine is if I really do still have a rootkit remaining after the hard drive reformat or is this just some anomaly? All help would be appreciated.

Thank you...

Hello having run ComboFix we need to see that and a DDS log.

Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9 which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
Skip the GMER step and instead post the ComboFix log you posted earlier.

Let me know if that went well.

Thanks for your assistance. I am on Step 8 (Create a GMER Log), and a rootkit was detected after running the scan. The problem I'm having is saving this to the desktop as the "ark.txt" file as directed. The only file type option shown is a "*.log". Even when I name it as "ark.txt", nothing is appearing as a saved file on my desktop. Can you please guide me on how to proceed. Thank you...

I'm sorry, I missed where you advised me to skip the GMER step. I have just attached the files:

- DDS
- Attach
- ComboFix log

in the location you advised me to. Thanks...

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic383045.html you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.
