MBR Alureon-K (RTK) - Need Help

Viruses and worms
1

Avast has found MBR Alureon-K (RTK) on my system. I am in the process of following your directions for tools and logs to speed up the process of getting clean. I ran SuperAntispyware Professional and it found Adware.IWin Games and BrowserHijacker.Favorites which have now been removed. I ran MBM Quick Scan and saved the log file to my desktop. I downloaded OTL to my desktop. When I attempted to run OTL, Avast found the file as suspicious and put it in Sandbox. Should I suspend my anti-virus softwares: Avast, SuperAntispyware and Threatfire while attempting to clean my system?

I’d like to get this right the first time.
Thank you.

No, when the autosandbox initially reacts have it ‘Open Normally’ and remember the answer for that program (OTL), see image example (click to expand).

Ok.
I ran the OTL scan and it saved Extras.Txt and OTL.Txt - Notepad to my desktop.
For the next step:
To attach : Within the post select:
Additional Options
Browse
Locate the OTL log
Select tthe OTL log

Where do I this? From My Computer? I have Windows XP.

Thanks.

see the box you type text in here…

just below the text i am typing now there is a “Attachment and other options”

see attached screenshot

5

Ok. I understand now.
I have attached 3 logs.
Will do next step and post when finished.

6

Next log being attached.

There are 2 logs in the file because I thought the scan was finished but it wasn’t.

There is also an MBR.dat icon now on my desktop that wasn’t there before. I did not click on it.

I don’t know if I should download RogueKiller or not. If I have to do this, do I suspend my anti-viruses since it says Quite all programs?

Please advise.

Thanks.

Hi whilst I look at the logs lets see if this is not the variant that has aswMBR tagged

Copy aswMBR to your root drive i.e. C:\aswMBR.exe
Click Start > Run
Copy/paste the following command into the box and press enter

aswMBR.exe -ap 1

Once it has completed then reboot and re-run aswMBR and post the log here

Meanwhile I will look at the other logs

How do I copy aswmbr to my root drive?

Sorry but I’ve been at this for awhile and am not sure. I copied the aswmbr icon and it’s now in my C:\
but I don’t think that’s correct. How do I know if awsmbr.exe is there or not?

9

Thats it, the icon is the programme ;D

10

Uh Oh.

Windows cannot find awsMBR.exe

Now what? :frowning:

11

Should I be copying the .exe file to C:\Documents and Settings since that’s where all my log files were put?

Here are the results:

The contents exceeded the limit so I’m sending it as an attachment.

When doing the scan Avast Quarantined 8 items and gave the option to Report a false positive.

14

Looking better, what files did Avast quarantine ?

On completion of this run can you let me know what problems remain

Re-run TDSSKiller and when you get the following item select delete

\Device\Harddisk0\DR0 ( TDSS File System )

Then

Avast icon is no longer in my system tray but is still on my desktop.

Do I disable MBAM before re-running TDSSKiller?

16

No TDSSKiller is OK it is just that OTL stops all process and MBAM gets very uppity about that

We will fix the tray icon in a bit… And Avast was snagging the files that TDSSKiller was moving

17

So I don’t need to disable MBM?

Do I re-run TDSSKiller the same way as before? Changing parameters or just Start Scan?

18

Same method as before change parameters etc ;D

19

Re-ran TDSSKiller.

Threats found as shown in last section of attached file.

The only place I can see \Device\Harddisk0\DR0 is in Notepad.
Cannot delete it from there.

Hope you’re staying up late tonight :slight_smile:

Will wait for reply before re-running OTL.
