Infected with Win32:BAMITAL-X/browsing redirects

I recently noticed that my browsing (ie, FF) (google won't even connect) was being redirected to random pages. My installed virus scanner has found nothing. So I installed Avast and it found win32:bamital-x on explorer.exe and winlogin.exe. And of course it cannot repair these system files. No other items have been found.

Have since disconnected the system from the internet and using a USB drive to pass log files from it.

What annoys me is that I am typically uber-safe when browsing. Sucks to be me.

GMER keeps locking up on me. I will post it when I have it if this is important.

Hi Gringo,

Thanks for replying. I can understand, by reading this forum, that malware is a real issue and I can understand that its hard to get to everyone.

For better or for worse, I tried the Microsoft Security Essentials which scanned the system, identified the problem, and then claimed it could fix it. It did, and well and truly screwed the box to the point that it continually reboot itself. Based on Avast and the MSE the infected files were explorer.exe and winlogon.exe. My guess is that the MSE was not as smart as Avast which claimed it could not fix the files.

So my only recourse was to build a BartPE disk, boot, and copy over the winlogon.exe and explorer.exe from another system.

It "works" now but as other threads in this forum indicate there is no guarantee that I am free of this Trojan.

So my questions now are:
1. Is there any point in proceeding to waste your time?
2. Should I just rebuild a new disk and copy my data files from backup?
3. Other?

Thanks
DMC

Greetings

The other note I should add is that when I attempt to run add/remove programs it crashes. lets see if during the course of the clean up it clears up - if not remind me again so I can look into it

I Would like you to do the following.

Please print out or make a copy in notpad of any instructions given, as sometimes it is necessary to go offline and you will lose access to them.

Run Combofix:
    Please visit this webpage for download links, and instructions for running the tool:

    http://www.bleepingcomputer.com/combofix/how-to-use-combofix

    Please ensure you read this guide carefully and install the Recovery Console first.

    The Windows Recovery Console will allow you to boot up into a special recovery (repair) mode.
    This allows us to more easily help you should your computer have a problem after an attempted removal of malware.
    It is a simple procedure that will only take a few moments of your time.


    Once installed, you should see a blue screen prompt that says:
      The Recovery Console was successfully installed.
    Please continue as follows:
    • Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
    • Click Yes to allow ComboFix to continue scanning for malware.

    When the tool is finished, it will produce a report for you.

    Please include the report in your next post:

    C:\ComboFix.txt

"information and logs"
    In your next post I need the following
    1. Log from Combofix
    2. let me know of any problems you may have had
    3. How is the computer doing now?

Gringo

ComboFix did popup a "rootkit" detected. It rebooted and rescanned and the following log was generated. During this process, on several occasions, a dialog appeared that indicated that PEV.cfxxe has crashed.

The instruction at 0x7c911909 referenced memory at 0xfffffff8. The memory could not be read.

Hi Gringo,

Hope Earl has passed you by safely.

The eset claims to find nothing however it crashes before completion. So I have no formal report from eset. I have attached the error it displays.

I was looking into the add/remove programs issue (has similar error). Other control panel items are fine, so I got a copy of appwiz.cpl and replace the existing version in c:\windows\system32. No change as the error occurs in rundll32.exe.

The system runs "normally" except for not being able to run all/remove programs - at least as I have found so far. No redirects are occurring.

sfc /scannow:

It appears to scan, and then disappeared. Is there a report it outputs? Or if it did not popup warnings then I should not worry about it?

RKUnhooker:
This continues to crash and does not complete. One element that also crashes is a mysterious program that has what appears to be a random collection of characters and lives in c:\windows\system32. Each time I run RKUnhooker the number changes. Is this RKU or is it something I should be concerned about?

I have attached the error message.

Thanks
