Hello,

I have been struggling with the Vundo malware (at least that I think) for the past week. I have read many tips on this site and tried most of them. Today, I was going to try your instructions for ComboFix. But I could not disable McAfee. When I try to open McAfee, I get an "security message": "Your current settings do not allow this file to be downloaded". I also get this message when I try to download exe files (using Firefox). After I click OK on the security message (two messages), the McAfee window opens, but without any information (completely blank). After the second attempt to disable, ComboFix gave a warning, then continued to run. But it hung-up, with a message that a file could not be found.

My basic problem is a rogue dll (loaded as c:\windows\system32\zayitala.dll). So far, I have tried (both in "normal" mode and safe mode (as admin)):
1. using Spybot
2. using AdAware
3. SpySweeper
4. Malwarebyte Anti-Malware
5. Deleting the registry entries using both Hi-Jack This and Autoruns (again, both in normal and safe mode)
6. While in safe mode, shutting down explorer.exe, then using cmd prompt deleting the dll. The file just reappears. I do notice a strange hidden file called nukajawi (no extension) that also reappears after renaming.

I am getting ready to bite the bullet and image my system; my patience is almost gone!

Any body have other suggestions or comments.

Thanks for your help.

Please note the message text in blue at the top of this forum.

You should not be using Combofix unless instructed to do so by a Malware Removal Expert who can interpret the logs. It is a powerful tool intended by its creator to be "used under the guidance and supervision of an expert", NOT for private use. Combofix was never meant to be used as a general purpose malware scanner like SuperAntispyware or Malwarebytes' Anti-Malware. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again. Please read Combofix's Disclaimer.

Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Psuedo HJT Report as part of its log.

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

Start a new topic, give it a relevant title and post your log along with a brief description of your problem, a summary of any anti-malware tools you have used and a summary of any steps that you have performed on your own. An expert will analyze your log and reply with instructions advising you what to fix. After doing this, we would appreciate if you post a link to your log back here so we know that your getting help from the HJT Team.

Please be patient. It may take a while to get a response because the HJT 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 "bump" your post or make another reply until it has been responded to by a member of the HJT 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 HJT Team member is already assisting you and not open the thread to respond.

If after 5 days you still have received no response, then post a link to your log in the thread titled "Post in this thread when you haven't received an answer in five days.".
