Please help remove 'Threat: MBR:Alureon-K [Rtk]' !!!

Viruses and worms
1

Hi,

I’m not sure how I wound up with this virus, but it took control of my computer for a short while with a series of pop-up windows and it hid all files and programs on my computer. I was able to locate a download that helped to restore my computer to normal, or at least it appeared to be. However, when I run the Avast scan it keeps telling me I still have infected files and one of them I cannot move to the chest or remove from my computer. The file is MBR:\.\PHYSICALDRIVE0\Partition2. When I try to move it to the chest, it gives me the following error message: Error: The request is not supported (50). I have followed the steps I found at the following link http://forum.avast.com/index.php?PHPSESSID=3n2bh0aj9s4babirvdv1djf7t1&topic=53253.0, only the download aswMBR.exe does nothing when I double-click on it so I wasn’t able to run that scan. Below, and attached, are the results of my scans…please help!!!:

welcome to the forum.

A malware expert will give further instruction when one of them is online.

3

Thank you for posting your logs. Can you go to https://forum.avast.com/index.php?topic=53253.0 and also attach the aswMBR log to your next post as well?

After this, please do not make any further changes to your machine until the malware removal expert assists you. Do not sync anything to your machine, and try not to use it as well. Thank you.

Essexboy has been notified.

4

That is confirmed I will need the aswMBR log, also did you run the RogueKiller shortcut hijack fix ?

5

Thanks very much for your help in advance!

I would have posted the aswMBR log as well, but I’ve downloaded it to my desktop and attempted to run it multiple times and nothing ever happens. I’ve tried both double-clicking on it once it’s saved to my desktop, as well as running it immediately and it never runs. Any suggestions??

I did run the RogueKiller ‘fix shortcuts’.

6

try running it in safe mode

if no success…wait for Essexboys instructions…he will be back tomorrow…late UK time

7

Thanks for the tip. How exactly do I run it in safe mode?

8

Figured out how to start up in Safe Mode…still didn’t work. Any other suggestions??

9

You have 2 options:

  1. Delete the copy you have on your desktop and download a new copy in regular mode giving it a different name, then run it again (try regular mode first, if no success then try Safe mode).

  2. If you can’t run it at all, wait for Essexboy to instruct you further.

Could you re-run TDSSKiller please as it failed to complete, the log should be two or three times that size

Then do the following :

Go Start > Run and type in this command
diskmgmt.msc

This will open the disc managemnet console, could you screenshot that and attach it here please

13

The report from the 2nd run of the TDSSKiller is attached. Still trying to figure out how to get a screenshot of the disk management window for you to look at. Can’t seem to paste it here, and it’s too large to attach. Will keep trying…

Screenshot of disk management window attached.

OK that looks good Ta

Download and Install Combofix

16

The ComboFix log is attached. An update on my computer’s performance will follow shortly…

17

Running an Avast full scan now and it’s detected two infected file thus far. However, it did not begin with 1 infected file right at the beginning of the scan as it was before.

18

Are the infected files in OTL_moved files and qoobox ?

19

It has now found 3 infected files. I’ll let you know what the files are as soon as the scan is completed.

20

I’ve attached the Avast Scan Results that shows the 3 files that were infected. However, I was able to successfully move them to the ‘chest’ and then Avast ran a restart/reboot scan and found no infected files. Looks like I’m good to go?!! Cannot thank you enough, essexboy!!

Any other suggestions moving forward??
