Alureon-M[rtk]

Viruses and worms
1

hello support,

i have the Alureon-M[rtk] and do not know how to get rid of it.

i went here —http://forum.avast.com/index.php?topic=53253.0.

i have the mbam log and the OTL.txt and extras.txt.

i can not run aswMBR.exe i get an error : Window can not find specified file or path,
you may not have the right permissions.

i am the administrator and tried to run as administrator and still no luck.

help please,
Craig

Where did you save the aswMBR.exe file, if not desktop, where ?

You should be able to run it as the same account that you downloaded it (if it has admin permissions). You could also try running it from safe mode.

3

hello,

ty for the quick reply, no isaved it on the desktoop. i just received the error. i will try safe mode and see if i can run from there.

4

here is the last i selcted none in the dropdown of aswMBR.

thanks again,

craig

Whilst I’m not a malware removal specialist - In this case - [TDL4] ROOTKIT found:

http://i1224.photobucket.com/albums/ee362/Essexboy3/aswMBR%20shots/aswMBRFix.gif

This is normally the action taken:

  • run the aswMBR scan again then click “FIX” and reboot

However, if you wish to wait for one of the malware removal specialists to analyse the logs and decide a course of action, I don’t have a problem with that. Essexboy is normally on the forums from about 7pm UK time, now 4pm. Unless one of the other malware removal specialist in a time-zone closer to your own can pick up on this one.

thank you for your reply,

i saw in a previous post essexboy gave a custom fix for somone. i might feel more comfortable if he looked at it but, how do you get a hold of him.

should i just wait, or is there a way to pm him , fortunately i do not get viruses or
worm so i do not come here often.

thanks,

craig

as for the

the change from TDL to Alureon-M reported by avast.

i do not know what is going on do i have 2 rootkits or a variant?

craig

The custom fixes relate to the OTL log and will have to be analysed by him to be able to do that the aswMBR actions would be separate to the OTL custom fix.

I have PM’d him about this topic already, but it is likely to be about two hours before he is on the forums…

You haven’t got two rootkits, it is just that aswMBR sees it as TDL4 a form of MBR rootkit, that the normal Avast detection sees as alureon.

ty,

a reason why i am reluctant to just press the fix is becasue i have a dual boot system.

one for xp and one for w7.
thanks for pm’ing him.

craig

No problem, essexboy will advise regarding dual boot and fixing the MBR when he gets on-line.

11

Using aswMBR should not affect the dual boot but, lets use another one to kill it on the off chance

Warning This fix is only relevant for this system and no other, using on another computer may cause problems

Be advised that when the fix commences it will shut down all running processes and you may lose the desktop and icons, they will return on reboot

If you have Malwarebytes 1.6 or better installed please disable it for the duration of this run

Run OTL

thank you very much essexboy,

i ran otl and attached are 2 files, because after reboot i was prompted to run otl.exe and that created a file.

then i tried to run it from the desktop it crashed went into safe mode and ran it from the desktop and i created another text file.

i have meetings, i will have to do the tdss part in a couple of hours.

thanks again,

craig

13

OK see you in a bit

We will need to run another programme after TDSSKiller as there is another miscreant that does not want to go

14

hello essexboy,

i am reading and running tdss killer.exe.

but this:

•Ensure Cure is selected

i do not see anywhere
???

craig

15

There are drop down lists Where you see the Skip in the image 4 of essexboy’s post above, replicated here (click to expand). So Cure would be one of the options in the drop down list.

I believe that is the area essexboy means.

16

sorry i panicked and did not scroll down to see what to do if cure was not present.

anyway see attached.

17

is everything ok now???

18

You may have missed essexboy, it is now 12:15am in the UK so he will be in bed now. He will be back online around 7pm.

Whilst I’m not very familiar with the TDSS log, looking at the end of scan summary at the bottom of the log, it shows a Detected object count: 9 but 8 of those were skipped by user, so essexboy would certainly need to re-analyse the log.

There is one selected for cure:

16:46:04.0044 2904 \Device\Harddisk1\DR1 ( Rootkit.Boot.Pihar.b ) - will be cured on reboot 16:46:04.0044 2904 \Device\Harddisk1\DR1 - ok 16:46:04.0140 2904 \Device\Harddisk1\DR1 ( Rootkit.Boot.Pihar.b ) - User select action: Cure

So if you haven’t already rebooted, you should do so.

After the reboot check how the system is running, e.g. is avast still alerting, etc. ?

19

OK re-run TDSSKiller and when you get to the following item select delete

\Device\Harddisk1\DR1 ( TDSS File System )

THEN

Download and Install Combofix

Download ComboFix from one of the following locations:
Link 1
Link 2

VERY IMPORTANT !!! Save ComboFix.exe 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

[*]Double click on ComboFix.exe & follow the prompts.
[*]Accept the disclaimer and allow to update if it asks

[*]When finished, it shall produce a log for you.
[*]Please include the C:\ComboFix.txt in your next reply.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now
