Hello,

I've been removing viruses for people for quite some time, and I'm running into an issue that normally I'm able to resolve with relative ease. This time, however, I have one that's been really stubborn. Here's a breakdown:

- Computer had a fake antivirus.
- Ran Rkill then FixNCR so I could work. (Everything was being blocked)
- Ran Unhide
- Malwarebytes and TDSSKiller removed a ton of items. OS seemed healthy after these were ran.
- Ran Combofix. Received the three popups "You have ZeroAccess, infected TCP/IP Stack etc", "You have a rootkit, this will take some time", then finally "Combofix needs to reboot the machine".
- Computer reboots..... then nothing happens. It boots into Windows normally. Fake Antivirus does not appear. Internet works. Everything works. Combofix never commences it's scan.

Normally, when Combofix needs to reboot the machine because of a rootkit, it will start scanning as soon as Windows loads. This time, it does nothing.

Here's what I've tried after finding Combofix will not run:

- Shutting down Pev.3XE and various other combofix processes while it runs initially.
- Scanning/Running Hijackthis, GMER, AntiZeroAccess, FixTDSS, Superantispyware, RootRepeal, Norton 360. They all find nothing malicious.
- I've pulled the HDD and scanned it as an external device. Nothing found.
- I've blown out the restore points, ran fixboot and fix mbr
- bunch of other stuff I've probably forgotten

Despite all of this, Combofix simply will not run. It sits there, pops up the messages stating I have ZeroAccess/Rootkit, reboots the machine, then nothing happens.

Vista Home 32-bit. Dell XPS All-in-One.

Any advice would be greatly appreciated!

Hello having run ComboFix we need to see that and a DDS log.

Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9 which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
Skip the GMER step and instead post the ComboFix log you have if possilble.

Let me know if that went well.

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help. No one is ignored here.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.
If you are unable to create a log because your computer cannot start up successfully please provide detailed information about the Windows version you are using: What we in particular need to know is version, edition and if it is a 32bit or a 64bit system. [/b]
If you are unsure about any of these caracteristics, just let us know and we'll help you figuring it out. Please also tell us if you have your Windows CD/DVD handy.


Please include a clear description of the problems you're having, along with any steps you may have performed so far.

Please refrain from running tools or applying updates other than those we suggest while we are cleaning up your computer. The reason for this is so we know what is going on with the machine at any time. Some programs can interfere with others and hamper the recovery process.

Even if you have already provided information about your PC, we need a new log to see what has changed since you originally posted your problem.
We need to create an OTL Report
  • Please download OTL from one of the following mirrors:
  • Save it to your desktop.
  • Double click on the Posted Image icon on your desktop.
  • Click the "Scan All Users" checkbox.
  • In the custom scan box paste the following:
    msconfig
    safebootminimal
    activex
    drivers32
    netsvcs
    %SYSTEMDRIVE%\*.exe
    /md5start
    explorer.exe
    winlogon.exe
    wininit.exe
    hlp.dat
    /md5stop
  • Push the Posted Image button.
  • Two reports will open, copy and paste them in a reply here:
    • OTL.txt <-- Will be opened
    • Extra.txt<--Will be minimized

In the upper right hand corner of the topic you will see a button called Watch Topic.I suggest you click it and select Immediate E-Mail notification and click on Proceed. This way you will be advised when we respond to your topic and facilitate the cleaning of your machine.

After 5 days if a topic is not replied to we assume it has been abandoned and it is closed.
