Help!!! MBR: \\.\PHYSICALDRIVE0\partition4 ... Please help essexboy!

[PhillDante]

Hi there!
I seriously need help and I have no clue about what to do! I'm freaking out!

I've read a bit about it, and it has lead me here.

My avast alerts me to know that I have a rootkit Alureon at MBR: \\.\PHYSICALDRIVE0\partition4. I choose to delete it, but when it reboots it's still there. I'm scared if I do something wrong that I will lose everything.

Please help!

Hi,

Welcome to the forum! 

Please go here >>  http://forum.avast.com/index.php?topic=53253.0   Follow the instructions to download and run OTL, Malwarebytes and aswMBR.  Attach the logs that are created into your next reply. 

[PhillDante]

Hi!
I've attached the logs like you asked, but OTL didn't make an extras.txt and aswMBR doesn't want to run.

[jeffce]

Hi,

Since aswMBR won't run do the following...

Please download TDSSKiller

• Right-click and Run as Administrator TDSSKiller.exe
  
• Press Change Parameters
  
• Check the boxes beside Verify Driver Digital Signature and Detect TDLFS file system, then click OK.
  
• Click on the Start Scan button
  
  • Only if Malicious objects are found then ensure Cure is selected
    
  • Then click Continue > Reboot now
    
  • Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.
    
• Copy and paste the log in your next reply
• A report will be created in your root directory, (usually C:\ folder) in the form of "TDSSKiller.[Version]_[Date]_[Time]_log.txt". Please copy and paste its contents on your next reply.

Hi!

I've run TDSSKiller and I've attached the log.

Thanks for helping me!

[jeffce]

Hi,

Re-run TDSSKiller and when you see this entry...  \Device\Harddisk0\DR0 ( TDSS File System ) remove that as well.  Save the log that is created.
--------

Download Combofix from either of the links below, and save it to your desktop. 
Link 1
Link 2

**Note:  It is important that it is saved directly to your desktop**

--------------------------------------------------------------------

IMPORTANT - Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools. If you have difficulty properly disabling your protective programs, refer to this link here

--------------------------------------------------------------------

Right-Click and Run as Administrator on ComboFix.exe & follow the prompts.

When finished, it will produce a report for you. 

• Please attach the C:\ComboFix.txt for further review.

In your next reply please attach the logs made by TDSSKiller and ComboFix. 

[PhillDante]

Hi!

I ran TDSSKiller again, but found no malicious objects. I remember that there was one malicious object when I first ran it, which then I decided to cure. I don't know if that was it.

I also ran Combofix, but throughout the whole process it kept throwing a message that "Windows cannot find NIRKMD, make sure you typed the name correctly." I did turn of the antivirus programs, but for some irritating reason, McAfee (The pre-installed program that I did not bother subscribing to, because I like Avast better and had a licence for Avast already) did not want to exit and keeps popping up. Do you want me to run it again?

After Combofix, all my old icons (that disappeared when this calamity started) returned.

I've attached both logs.

Thanks for helping me so far, I feel like I'm beating this thing (with your help obviously )...

Hi!

I did what you told me and it generated another log. The same error message still appears though, probably about 20 times throughout the whole process. Is this something I should be worried about?

You usually make me attach the logs, but in your previous post you said that I should copy and paste the report. I tried to do it, but it exceeded the allowed character length.

I've attached the log.

[jeffce]

Hi,

Don't worry about the error.  It has to do with ComboFix. 
----------

Ok...let's remove McAfee first...

Download and run the tool found here >> http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe  to remove McAfee.
---------

Please delete the current version of Combofix.exe from your desktop and download a new version from here to your desktop.

Disable your AntiVirus and AntiSpyware applications.

• Please open Notepad (Start -> Run -> type notepad in the Open field -> OK) and copy and paste the text present inside the code box below:
  

Code: [Select]

RegLock::
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E96D-E325-11CE-BFC1-08002BE10318}\0000\AllUserSettings]
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E96D-E325-11CE-BFC1-08002BE10318}\0001\AllUserSettings]


• Save this as CFScript.txt and change the "Save as type" to "All Files" and place it on your desktop.

Hi!

I've done everything and attached the report. Got rid of McAfee. The error didn't show this time, which was a relief. Did disable avast, but it said that it was still active (even though it wasn't).

[jeffce]

Hi!

I've attached the logs from Malwarebytes and ESET.
How many scans and logs do I still need to do? It seems like everything is back to normal and I haven't received any security notifications or any of those thing for a long time.

Hi!

I did the JavaRa thing and installed the latest JRE.
I also did the quick fix with OTL and then did a new scan after it rebooted.

Logs are attached.
