Cannot remove mrxdavv.sys & kwave.sys

Recommended Posts


I would greatly appreciate some help with my problem.

I have been trying to fix my Dad's computer but I cannot manage to do it. The computer shows no obvious signs of infection, such as pop-ups or fake antimalware screens etc. But when I run MBAM it continually finds two rootkit/trojan files (mrxdavv.sys & kwave.sys) which are scheduled for deletion on reboot. However, after rebooting, MBAM still finds these two files.

I have already run ComboFix, which must also have found these same two files, because the ComboFix log also says that it has deleted both of the files. But when I ran MBAM afterwards, MBAM found these same two files once again. So I assume that neither MBAM or ComboFix has been able to successfully delete them.

I cannot see the mrxdavv.sys & kwave.sys files with file explorers in either normal Windows or Windows Safe Mode. But I sort of expected this because I thought they might be hidden by the rootkit. But I have also booted the computer with an ERD commander Boot CD, and I cannot even see the mrxdavv.sys & kwave.sys files with file explorers in a Windows PE environment either. So I was wondering if these two files are created, and also hidden, at boot time - or something like that. I suppose a bootlog might tell me something useful. But anyway, I have already exhausted my tiny amount of computer knowledge, so now I think it's wise for me to leave it to the experts.

I have pasted the ComboFix, HijackThis and MBAM logs for analysis.

Thanks in advance.

I've just realised that I ran ComboFix without installing the Recovery Console. Sorry about that. Should I let ComboFix install the Recovery Console, run it again, and post some more logs?

I'm sorry for posting again within 48 hours, but I thought I'd better mention the ComboFix/Recovery Console mistake that I made. :huh:

Hi AdvancedSetup, thanks for helping me.

I've just got back from my Dad's house. Whilst I was there, I ran a quick scan with MBAM 1.40 and it found the same two mrxdavv.sys & kwave.sys rootkit/trojan files which needed to be deleted on reboot. After rebooting I ran another quick scan with MBAM 1.40, which found these same two files again. Then I upgraded to MBAM 1.41, ran an update, and ran another quick scan. But this time the scan was completely clean with no malicious items detected. Here is the new log:

I did notice something about a 'junction problem' in MBAM 1.40 which was fixed in MBAM 1.41, so I'm wondering if it was something to do with that?

Anyway, everything seems to be fine now, so that's great. :unsure:

I also updated NOD32 and ran a full virus scan, which also found no problems.

Is my Dad's computer OK now? Or do I need to do anything else?

The junction issue was only due to a semi rare issue on Vista not XP.

Well if NOD32 came back clean and MBAM now comes back clean that's a good thing. It's possible that it was a false positive that was also fixed.

If there are any signs of infection still or you're still concerned then we should probably have you run this scan from Combofix.

Please download ComboFix from Here or Here to your Desktop.

**Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved and renamed following this process directly to your desktop**

  1. If you are using Firefox, make sure that your download settings are as follows:
    • Tools->Options->Main tab
    • Set to "Always ask me where to Save the files".

[*]During the download, rename Combofix to Combo-Fix as follows:



[*]It is important you rename Combofix during the download, but not after.

[*]Please do not rename Combofix to other names, but only to the one indicated.

[*]Close any open browsers.

[*]Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.


  • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
  • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.


  • Close any open browsers.
  • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
  • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
  • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.


[*]Double click on combo-Fix.exe & follow the prompts.

[*]When finished, it will produce a report for you.

[*]Please post the "C:\Combo-Fix.txt" along with a new HijackThis log for further review.

**Note: Do not mouseclick combo-fix's window while it's running. That may cause it to stall**

If you still cannot get this to run, try booting into Safe Mode, and run it there.

To boot into Safe Mode, tap F8 after BIOS, and just before the Windows logo appears. A list of options will appear, select "Safe Mode."

If this doesn't work either, try the same method (above method), but name Combofix.exe to iexplore.exe instead, or winlogon.exe..

This because It also happens in some cases that malware blocks EVERY process except for what is in its own whitelist, so this whitelist also includes system important processes such as iexplore.exe, explorer.exe, winlogon.exe...

Thanks for your advice, AdvancedSetup. I think everything is OK now.

I ran CCleaner, which deleted about a gigabyte of unnecessary stuff. Then I ran ComboFix, which did not find anything to delete. An MBAM scan also was completely clean. And also an F-Secure Online Scan was completely clean as well.

Thanks again for your help. :unsure:

Well up to you but without logs to see not much I can say. If you're satisfied then I'll go ahead and close the post and leave you with this information and suggestions.

So how did I get infected in the first place?

At this time your system appears to be clean. Nothing else in the logs indicates that you are still infected.

Now that you appear to be clean, please follow these simple steps in order to keep your computer clean and secure:

Remove all but the most recent Restore Point on Windows XP

You should
Create a New Restore Point
to prevent possible reinfection from an old one.

Some of the malware you picked up could have been saved in System Restore.

Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point.

Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to
to a clean working state.

The easiest and safest way to do this is

  • Go to
    System Tools
    and click "
    System Restore

  • If the shortcut is missing you can also click on
    > and type in
    and click OK

  • Choose the radio button marked "
    Create a Restore Point
    " on the first screen then click "

  • Give the new Restore Point a name, then click "

  • The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.

  • Then use the
    Disk Cleanup
    to remove all but the most recently created Restore Point.

  • Go to
    and type:

  • Select the drive where Windows is installed and click "
    ". Disk Cleanup will scan your files for several minutes, then open.

  • Click the "
    More Options
    " tab, then click the "
    Clean up
    " button under System Restore.

  • Click Ok. You will be prompted with "
    Are you sure you want to delete all but the most recent restore point?

  • Click
    , then click Ok.

  • Click
    again when prompted with "
    Are you sure you want to perform these actions?

  • Disk Cleanup will remove the files and close automatically.

  • On the
    Disk Cleanup
    tab, if the
    System Restore: Obsolete Data Stores
    entry is available remove them also.

  • These are files that were created before Windows was reformatted or reinstalled. They are obsolete and you can delete them.


Additional information

Microsoft KB article: How to turn off and turn on System Restore in Windows XP

Bert Kinney's site: All about Windows System Restore

Here are some free programs I recommend that could help you improve your computer's security.

Install SpyWare Blaster

Download it from here

Find here the tutorial on how to use Spyware Blaster here

Install WinPatrol

Download it from here

Here you can find information about how WinPatrol works here

Install FireTrust SiteHound

You can find information and download it from here

Install hpHosts

Download it from here

hpHosts is a community managed and maintained hosts file that allows an additional layer of protection against access to ad,

tracking and malicious websites. This prevents your computer from connecting to these untrusted sites

by redirecting them to which is your own local computer.

hpHosts Support Forum

Update your Antivirus programs and other security products regularly to avoid new threats that could infect your system.

You can use one of these sites to check if any updates are needed for your pc.

Secunia Software Inspector

F-secure Health Check

Visit Microsoft often to get the latest updates for your computer.


Note 1: If you are running Windows XP SP2, you should upgrade to SP3.

Note 2: Users of Norton Internet Security 2008 should uninstall the software before they install Service Pack 3.

The security suite can then be reinstalled afterwards.

The windows firewall is not sufficient to protect your system. It doesn't monitor outgoing traffic and this is a must.

I recommend Online Armor Free
