Normally my set of tools and preserverance gets me through and I elimate all signs of a virus but this is the hardest one I've ever tried to get off my computer.
I've followed instructions from another thread where some had the same problem but mines just doesn't follow the pattern. haxfix does not delete it. I can't quarantine it within Security Task manager. I deleted AVG hoping to reinstall it but the trojan stops all programs from working properly. I've even deleted all the registry commands from this guide.

Delete the following files:

Delete the following registry subkeys: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\vistaj
Delete the following registry subkeys: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon\Notify\vistax\"DllName" = "vistax.dll "
NT\CurrentVersion\Winlogon\Notify\vistax\"Startup" = "CxaEqsData"
NT\CurrentVersion\Winlogon\Notify\vistax\"Impersonate" = "1"

except I can't find these entries


I did manually delete vistax.dll and vistaj.sys from the command prompt by booting up from my secondary harddrive. At the moment I can log in to my infected drive but I remove the broadband conection.
Any help would be appreciated, thank you.

Hi Gunblade

That's a nasty one!


I suggest you post a HijackThis log for examination.

A member of the HijackThis Team will walk you through, step by step, how to disinfect your computer.
Once you post your log, don't make any changes to your system, as that could change the results of the posted log, making it difficult to properly clean your system.

Please read, and follow, all directions carefully!!!

Read Preparation Guide for use before posting a HijackThis Log.

Then, run a log, and post it in the HijackThis forum, at this link. Do not, fix anything, yet.
A member, of the HJT Team, will help you out.It may take a while to get a response, because the HJT Team are very busy. Please, be patient, as these people are volunteers. They will help you out, as soon as possible.

Once you have made the post, please, DO NOT make another post in the HJT forum, until it has been responded to by a member of the HJT Team.
The first thing they look for, when looking for logs to reply to, is 0 replies.
If you make another post, there will be 1 reply.

The team member, glancing over the replies, might assume someone is already helping you out, and will not respond. So, just make your post, and let it sit there, until a team member responds. This way you will be taken care of, in the most timely manner.

Did you "unhide "hidden files? Did you try any online scan?Ewido or Bitdefender The last reort would be a HJT log. please read and follow all instructions in the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". You may have performed some of these steps already. About half way down are instructions for downloading HijackThis and creating a log.

When you have done that, post a log in the HijackThis Logs and Analysis 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. Please include the top portion of the HijackThis log that lists version information. An expert will analyze your log and reply with instructions advising you what to fix.

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 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 HJT log here.

After posting a log 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 HJT Team member. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make may cause confusion for the member assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

Haxdoor is an advanced kernel-mode rootkit that injects its hooks to the user-mode from the kernel. Some variants will include a rootkit driver in your System32 folder and it can be difficult to remove without some assistance and special tools. You should post a log as soon as you can.
