Hi. I had a pc infected with TDL4, which combofix detected (none of all of the other apps i've tried including MBAM, SAS, ESET, Avira, and many others found it..). The GMER Mbr rootkit detection tool included in combofix found the rootkit in the mbr. To fix it, i've used TDSSKiller, which found and 'cured' it.

However, on reboot, the computer is in a reboot loop. The safe mode wont boot up either.

Computer is running Win7 32 Bits. I've tried doing a recovery using 'Repair my computer' from the boot cd, won't work.

What did TDSSKiller mess with, only the MBR (since it's the only place it found something about the TDL4 rootkit..) ?

I'm wondering what are the options here to get this box working. Thanks for any advice !

BTW, the issue was redirections in any web browser to stop-malware-website.com !

Hello.

I think it's best for your computer, to threat that infection. Just follow the steps on http://www.bleepingcomputer.com/forums/topic34773.html (Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help).

When post your (Hijackthis log +) DDS Log:
  • Do not post it at this topic or this forum but on http://www.bleepingcomputer.com/forums/forum22.html
  • Be patient, it's very busy at this forum.
  • A professional expert will view your logs and will help you with that problem.
  • Do not use tools (like ComoFix) without professional experience/helper.
Good luck.

Hi Driesioo; i think you missed 1 or some parts of what happens here. I can't run DDS or HJT, the computer is currently not booting after running TDSSKiller to remove the TDL4 infection.

Read my original post carefully ! Thanks.

Non-booting PCs sometimes happens after removal of these pests.

You should still post at the Malware forum. If you are unable to post any logs this should be explained and a link to the topic here should also be added.

Now that you have posted in the logs forum, 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 Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it 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 Malware Removal 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 Malware Removal Team members are very 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 Malware Removal 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 MR Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.
The power of accurate observation is commonly called cynicism by those who haven't got it.
