Hi pimse,

Alcohol 120 is installed on this computer


After extensive research, I have found that the visible symptoms – system slowdown, evidence of mbr rootkit and atapi.sys locked can be caused by Alcohol 120

If you have the license key necessary to reinstall Alcohol 120 then please uninstall it, reboot and then run look.bat.

If this still indicates a rootkilt infected mbr then please reboot into the Recovery Console and run fixmbr then reboot to normal mode and run look.bat.

Please post the results from look.bat in your next reply.

Alcohol is uninstalled now

Lookbat log after reboot:

fixmbr resulted in a successfully written mbr, but the log looks like:

It seems to be a real hard one to disinfect.

Is this of any interest?

Nod 32 blocked some activity for a moment ago. No human activity, the computer did by itself.

Hi pimse,

Indeed it does, we will fix it eventually.

Let's keep Alcohol off for now as we can reinstall once all is sorted.

It's a holiday weekend in the UK so I will be away from home with slow Internet access but be assured that I will keep with this problem until it is resolved (my replies may be limited until Monday).

Let's set a new baseline to work from after the changes we have made so far, please run a new Combofix scan and post the log.

I think there is one thing you should know.
My concern about my computer is not C:, the systempartition. It is the other partitions my concern is about.

I got a image of C:, so I am able to restore it to somewhat status like it is now.
It is possible i must do so after the third run of Combofix if the going follows the earlier pattern.

Here's the latest combofix log, and not the slightest trouble to get it! :P

Hi pimse,

Finally I managed to run GMER in normal mode


Good, and that log is clean.

I have been in discussion with the experts of this forum and the consensus is that results of the tests we have done so far indicate that the symptoms are that of CD emulation software and not of a rootkit mbr infection.

I agree with these findings and plan to undo the changes that we have made and return the system to the state is was when we started.

If however you wish to verify the above then the next stage will be to completely uninstall CDBurnerXP and ImDisk along with any other software that may provide CD emulation functionality.

This may still not remove the symptoms as the uninstall may not remove all the changes that those programs have made to the system.

Please let me know how you would like to proceed.

Hi deltalima,

I think it would be nice if it is possible to verify that it is CD emulation apps that causes the detection. (I hope that was English enough to be understood).

CDBurnerXP and ImDisk, have you seen any other?

Thanks

Hi pimse,

Please uninstall those while I check your uninstall list for any more. One note, Alcohol 120% did not show in that list so it may be worth checking the start menu to see if anything shows there that is not in the uninstall list.

Hi deltalima,

Now I have gone through the startmenu and the program files directory and uninstalled CDburnerXP, Imdisk, Imgburner, GameJackal. I have run fixmbr in recovery console and after reboot I run Look.bat and the log looks like:

Stealth MBR rootkit/Mebroot/Sinowal detector 0.3.7 by Gmer, http://www.gmer.net

device: opened successfully
user: MBR read successfully
called modules: ntkrnlpa.exe CLASSPNP.SYS disk.sys ACPI.sys hal.dll >>UNKNOWN [0x8A8FCE58]<<
kernel: MBR read successfully
detected MBR rootkit hooks:
\Driver\atapi -> 0x8a8fce58
Warning: possible MBR rootkit infection !
user & kernel MBR OK
copy of MBR has been found in sector 30 !
Use "Recovery Console" command "fixmbr" to clear infection !


The computer is running good now, it is fast booting and opening Firefox rather quick. It feels good, except for the knowledge about the content of the log above. But I will keep it in mind and also hoping that the force may be with me.

Hi pimse,

That's good to hear.

It feels good, except for the knowledge about the content of the log above.


I understand your concerns, but please be assured that rootkit detection is difficult and prone to false positives, this thread has been reviewed by several experts from the antimalware community who all agree that the system is clean.

Remove GMER

Delete the GMER icon from your desktop.

Delete the TDSSKiller icon, folder and zip file from your desktop.

Delete the look.bat from your desktop.

Uninstall ComboFix

  • Click START then RUN
  • Now type Combofix /Uninstall in the runbox and click OK

Clean up with OTL

  • Double-click OTL.exe to start the program. This will remove all the tools we used to clean your pc.
  • Close all other programs apart from OTL as this step will require a reboot
  • On the OTL main screen, press the CleanUp! button
  • Say Yes to the prompt and then allow the program to reboot your computer.
