About a week ago, while searching for a trial version of a .dwg to .pdf converter to run on my HP Pavilion zd8000, running Windows XP Media Edition, Service pack 2, I apparently downloaded this virus. Immediately started getting the bogus search results associated with this infection and all sorts of popups about how my antivirus was disabled and etc, etc...
I tried to run Malwarebytes...no go.
I tried to restore to an earlier date...no go.
I started searching for options, switching between Chrome, IE and Firefox to find real search results. Found this forum, down loaded tdsskiller and ran it. It identified the above mentioned virus and the fact that it was counterfeiting an AFD.sys file and an mrxsmb.sys file. TDSSKilller could only "cure" the mrxsmb issue, the other returned "processing error" results. I tried running MBAM, it wouldn't let me. I tried renaming the exe file, it told me I didn't have those permissions. I turned it off and let it sit for the weekend while I worked.

I have a friend who is a long time systems admin for mid size corporation. Went to his house last night, with the notion of possibly using his clean boot disk as a way around. No go. He spent some time searching this forum and we tried several things in a effort to get this thing off my computer. The newest wrinkle is that the computer hangs while "Acquiring Network Address" and I can't get online with it. In fact, I'm writing this on my girlfriend's Mac (and don't think I'm not getting crap about THAT!)
So, that's the problem. What I need to know is whether or not I can recover from this point. I can access this forum through the Mac I'm using now and can access the software you will want me to download, what I don't know is if I can download that software to a flash drive and then use it on my PC, or will the Mac want to convert everything to it's file system before it loads it on the flash drive, rendering it unusable on my computer.

Thank you for taking a look, I look forward to hearing from someone.

You have a serious malware infection. Disinfection will probably require the use of more powerful tools than we recommend in this forum. Before that can be done you will need to create and post a DDS log for further investigation.

Please read the "Preparation Guide".
  • If you cannot complete a step, then skip it and continue with the next.
  • In Step 7 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.
When you have done that, post your log in the Virus, Trojan, Spyware, and Malware Removal Logs forum, NOT here, for assistance by the Malware Response 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 Malware Response 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, please reply back here with a link to the new topic so we can closed this one.

It will take me several days to get back to a PC where I can download the required software, transfer the software to my computer, run the programs, create the logs and post them. Unless someone can tell me how to download the programs to a Mac so they will transfer to my PC.

In a situation such as this, you can download the programs to removable media such as a flash drive. You can then install the programs on the computer that requires them from the flash drive. I have done this before when I couldn't wait for a IBM compatible computer in the computer clusters at the university and used a Mac instead. I've even worked on the same word document on both a Mac and an IBM compatible computer.

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/topic413368.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.
