Nasty little virus

Hokay,
So here is my situation.
Avast picked up a virus a couple of days ago. I deleted it, ran a bootscan and thought nothing more of it. It was identified as a trojan, I of course didn't write down the name.
Boot up the computer to....a whole mess.

Most of my programs won't run, but I have a stable desktop. Programs that aren't starting (at startup) include Intel Extreme Tuning Utility, Catalyst Control Center, Steam, Dropbox, and importantly Avast. Windows firewall seems to be working. I can later activate the control center, but none of the others. Neither Firefox nor Chrome work. I can run any windows component program and winRAR (and those without error, issue, or erroneous behavior) including IE and media center. I cannot run windows update, though my computer says that there is an update to be installed. Windows defender finds nothing wrong on full system scan. When I try to start avast through system services, I get an error that states that the program failed to respond to the start or command request in time (almost instantaneous error). I can't sidestep that dialogue box.

For clarification, when I say doesn't work, I mean I try to activate the program and nothing happens (outside of the briefest of hourglasses indicating that yes, I did in fact double click).

Nothing is overly suspicious in running processes.

I know that the worm is messing with my registry in some way, looking for possible culprits in add/remove programs gives the dialogue that the program has been removed previously, do you want to delete the registry file. This dialogue appears for every program on the computer. There is no uninstall, and agreeing to remove the registry entry does nothing. I can add and remove windows components like normal. ActiveX also appears to be disabled--bit defender browser scan does nothing. I am on 64 bit windows, and dds does not work. System restore did nothing.
And of course the big kicker...windows freezes when attempting to boot into safe mode. Gets a chunck of booting done, then just stops.

I am creating an Ubuntu boot disk to run a scanner, but I have the distinct feeling that this guy is already outside my price range and linux results nonwithstanding, addition removal/cleanup will be required. I will post results of boot disk as soon as I have them, but until then any comments and advice would be appreciated.

Hello,

Please follow the instructions in ==>This Guide<== starting at step 6. If you cannot complete a step, skip it and continue.

Once the proper logs are created, then post them in a reply to this topic by using the Add Reply button.

If you can produce at least some of the logs, then please create the post and explain what happens when you try to create the log(s) that you couldn't get. If you cannot produce any of the logs, then still post the reply and explain that you followed the Prep. Guide, were unable to create the logs, and describe what happens when you try to create the logs.

Please note that I am not a member of the Malware Removal Team and will not be assisting you in removing the infection. I'm simply helping you to post the information they need in order to assist you.

Unfortunately, I had to go nuclear with this virus

DDS got to the point of run/cancel popup dialogue but nothing after that
I am running 64bit Windows so that would be the only log I could do

I attempted to scan via ubootin
When booting from kapersky rescue disk, no hard drive was recognized
When booting from USB ubuntu (both pendrive creator and ubootin), I could not access linux as they claimed corrupt kernel.
I am not sure whether this was because of a deeply embedded worm or because of some other issue

I had an image from 4/2010 (firefox 3.5!) on an external drive, and given that I was working mostly from a netbook with bad internet, I went nuclear and re-imaged

BUT

knowing full well that without the ever important logs diagnosing the virus is quite difficult (if not impossible)
I need an opinion on whether a BIOS reflash is in my future
Or what I can run to tell.
Thank you very much.

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.

    • If you were unable to produce the logs originally please try once more.

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

You have stated that you no longer need help with this issue, therefore I am closing this topic. If that is not the case and you need or wish to continue with this topic, please send any Moderator a Personal Message (PM) that you would like this topic re-opened.
