Title: MBR : \.\\PHYSICALDRIVE0\PARTITION2
Post by: willo.c on March 29, 2012, 07:04:46 PM
Avast continues to say that I have a virus: MBR Alureon-k in MBR physicaldrive0 Partition2
I'll send the log both from OTL, but aswMBR doesn't work on my PC.

Hope you can help me.
Thanks in advance,

Hi, 

Please download aswMBR (http://public.avast.com/~gmerek/aswMBR.exe) to your desktop.

Jeff,

Thanks for consideration, but it simply doesn't work..
I tried to run it.. But it doesn't start..

I also take a look in the processes: for few seconds the aswMBR process is present and then it simply disappears without any view of the tool Windows in which we have the scan button..

Hi willo.c,

Let's try this...move aswMBR to your C:\ folder so that it will look like this when there >>  C:\aswMBR.exe  Try to run it from there.  If it still doesn't work boot to Safe Mode and try to run it from there.

If renamed in explorer.exe it showed:

The application failed to initialize properly (0xc0000005). Click on OK to terminate the application.

Already tried TDSSKiller, but it doesn't start, exactly as aswMBR...

Hi,

Let's go about this another way.  Underneath my name over to the left...you will see a "Globe" icon.  Press that and go to my page.  Once there, select the file named svchost and download that file directly to your C:\ folder and then run the program.  If a log is produced post that to your next reply.  :)

Post by: willo.c on April 01, 2012, 08:27:06 PM
Jeff,

always the same problem.. Nothing happens..
Is it the aswMBR renamed?
Title: Re: MBR : \.\\PHYSICALDRIVE0\PARTITION2
Post by: jeffce on April 01, 2012, 09:14:54 PM
Let's take a look and see what we have

In the run box type the following

diskmgmt.msc

When disc management opens expand it so that all drives are visible
Take a screenshot and post it here

Are you able to burn a CD on another computer ?
Title: Re: MBR : \.\\PHYSICALDRIVE0\PARTITION2
Post by: willo.c on April 01, 2012, 09:35:17 PM
Attached the screenshot..

Of course, i can burn a CD/DVD on another pc..

Hi,

I need you to download:
gparted-live-0.10.0-3.iso (http://sourceforge.net/projects/gparted/files/latest/download?source=files) (115.1 MB) 

Create a bootable CD, for Gparted from the ISO image.

You can use ImgBurn (http://download.imgburn.com/SetupImgBurn_2.5.6.0.exe) do this.

Now boot off of the newly created Gparted CD. 

(http://img829.imageshack.us/img829/5772/gpartedsplash.th.png)

You should be here... Press ENTER

(http://img5.imageshack.us/img5/7286/gpartedkeymaps.th.png)

By default, "do not touch keymap" is highlighted.
Leave this setting alone and just press ENTER. 

(http://img404.imageshack.us/img404/9840/gpartedlanguage.th.png)

Choose your language and press ENTER. English is default [33]

(http://img140.imageshack.us/img140/7958/gpartedgui.th.png)

Once again, at this prompt, press ENTER 
You will now be taken to the main GUI screen below

(http://img32.imageshack.us/img32/1122/gpartedo.th.png)

According to your logs, the partition that you want to delete is 10mb

Click the trash can icon to delete and then click Apply.

You should now be here confirming your actions: 

(http://img233.imageshack.us/img233/1533/gpartedsteps.th.png) 

Now you should be here:

(http://img696.imageshack.us/img696/8471/gpartedsuccessclose.th.png) 

(http://img194.imageshack.us/img194/7753/gpartedboot.th.png)

Is "boot" next to your OS drive? 
If "boot" is not next to your OS drive under "Flags", right-mouse click the OS drive while in Gparted and select Manage Flags 

In the menu that pops up, place a checkmark in boot like the picture below:

(http://img196.imageshack.us/img196/3483/gpartedmanageflagsboot.th.png) 


Now double-click the (http://img822.imageshack.us/img822/641/gpartedexit.png) button. 

You should receive a small pop up like this:

(http://img88.imageshack.us/img88/8986/gpartedexitreboot.png)

Choose reboot and then press OK.

Jeff,

i deleted the small partition... Now everything is OK!!! :))
Avast don't find anything.. Even Malwarebytes don't find anything..

Thanks a lot!! ;) ;) ;)

Is there something i can do to prevent any other rootkit?
Title: Re: MBR : \.\\PHYSICALDRIVE0\PARTITION2
Post by: jeffce on April 02, 2012, 06:37:02 PM
Oh now stay with me...there was more on your system than just that.

Were you able to get aswMBR to run?  If so please post that log.  I want to make sure your system is on the up-and-up.  :)
Title: Re: MBR : \.\\PHYSICALDRIVE0\PARTITION2
Post by: willo.c on April 02, 2012, 08:14:51 PM
 :( :( :(

You were right..

Now the process Services.exe is running on my CPU over 90%..

But i'm able to run aswMBR.. I'm going to post the log when it finishes the scan..

Malwarebytes

I see that you have Malwarebytes already on your computer.  Please open Malwarebytes, update it and then run a Quick Scan.  Save the log that is created for your next reply.

ESET Online Scanner
I'd like us to scan your machine with ESET Online Scan

Note: It is recommended to disable on-board anti-virus program and anti-spyware programs while performing scans so there are no conflicts and it will speed up scan time.
Please don't go surfing while your resident protection is disabled!
Once the scan is finished remember to re-enable your anti-virus along with your anti-spyware programs.



As a Vista/Win7 user you will need to right click your browser icon and select "Run as Administrator" in order to run this scan.

ESET OnlineScan (http://eset.com/onlinescan)

scanning your computer. Please be patient as this can take some time.

Jeff,

Remember the process services.exe is still running and it takes almost all my cpu, at least in Normal mode.
In safe mode i cannot disable completly my antivirus.. And it is always difficult to run something..

I try to do the steps you kindly suggest me..
I keep you informed..

Hi,

Let's get a fresh scan and try to see what is using all that...

Run a new scan with OTL
In Custom Scans/Fixes put the following:

netsvcs

Press the Run Scan button and attach the logs created. 
Title: Re: MBR : \.\\PHYSICALDRIVE0\PARTITION2
Post by: willo.c on April 05, 2012, 02:29:05 PM
Here the OTL log done in Safe Mode, because i can-t go to an end in Normal mode..

Consider that services.exe take 50-60 % of CPU in Safe Mode, and 85-95% in Normal mode..

In your opinion, do I have to format C?
Title: Re: MBR : \.\\PHYSICALDRIVE0\PARTITION2
Post by: jeffce on April 05, 2012, 06:10:41 PM
I am not sure about formatting yet.  :)

You never mentioned whether or not you are still using ZoneAlarm.  In my experience that can be quite a resource hog.
Title: Re: MBR : \.\\PHYSICALDRIVE0\PARTITION2
Post by: willo.c on April 05, 2012, 06:14:57 PM

I think this is not Zonealarm.. If I stop it nothing happens..
Could it be avast? And is there a problem to formatting?

No there is not a problem at all.  As a matter of fact I recommend it every so often just to have a clean start and make sure everything is fresh and running right.  With the infection that you had, if it were my computer, I would format...but that is just me.
