Hello,

A few weeks ago, I was infected with a variant of the Virtumonde virus. I'm using Windows XP Home (SP 3) and was browsing in Firefox (3.0.10) when I witnessed what seemed to be a browser redirect infection (maybe, I'm not sure because I'm not an expert on this).

I ran Spybot S&D and what came back (in part) was:

Microsoft.WindowsSecurityCenter.FirewallBypass: [SBI $D80580B5] Settings (Registry value, fixed)
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\FirewallPolicy\StandardProfile\AuthorizedApplications\List\C:\WINDOWS\explorer.exe

Virtumonde.Dll: [SBI $49C83B55] Browser helper object (Registry key, fixed)
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{69241f6f-9f59-4101-bd08-2f8b5a23b6b7}

Virtumonde.prx: [SBI $85112C1D] Autorun settings (gajivakomo) (Registry value, fixed)
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\gajivakomo

Then I ran it again and got the following info (in part):

Virtumonde.prx: [SBI $85112C1D] Autorun settings (gajivakomo) (Registry value, fixed)
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\gajivakomo


Then I ran MBAM and got the following info (in part):

Registry Keys Infected:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{69241f6f-9f59-4101-bd08-2f8b5a23b6b7} (Trojan.Vundo.H) -> Quarantined and deleted successfully.
HKEY_CLASSES_ROOT\CLSID\{69241f6f-9f59-4101-bd08-2f8b5a23b6b7} (Trojan.Vundo.H) -> Quarantined and deleted successfully.

Registry Values Infected:
(No malicious items detected)

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Security Center\UpdatesDisableNotify (Disabled.SecurityCenter) -> Bad: (1) Good: (0) -> Quarantined and deleted successfully.


Afterward, all went well and I thought I had the thing beat, but in a regular scan with Spybot S&D yesterday, up came the following infection information:

Virtumonde.sdn: [SBI $70056CE6] Data (File, fixed)
C:\WINDOWS\SYSTEM32\vuyitetu
Properties.size=0
Properties.md5=D41D8CD98F00B204E9800998ECF8427E

Virtumonde.sdn: [SBI $84B4F97A] Data (File, fixed)
C:\WINDOWS\SYSTEM32\gedofano.exe
Properties.size=0
Properties.md5=D41D8CD98F00B204E9800998ECF8427E

And then today, two alerts from ZoneAlarm Security Suite concerning Packed.Win32.Krap.q virus, which was trying to launch itself. ZoneAlarm caught it and quarantined it, but I find this latest return of hits to be very suspicious. Am I still infected? My regular and daily scans with MBAM come up negative and I have the paid version with protection module enabled and even have a full scan scheduled to run each day.

Any thoughts/help on this would be greatly appreciated.

Hi and welcome to BC! When you run MalwareBytes, make sure the teatimer setting is temporarily turned off. Let's take a look with this tool...

Install RootRepeal

Click here - Official Rootrepeal Site, and download RootRepeal.zip. I recommend downloading to your desktop.
Fatdcuk at Malwarebytes posted a comprehensive tutorial - Self Help guide can be found here if needed.: Malwarebytes Removal and Self Help Guides.
Click RootRepeal.exe to open the scanner.
Click the Report tab, now click on Scan. A Window will open asking what to include in the scan.
Check the following items:
Drivers
Files
Processes
SSDT
Stealth Objects
Hidden Services

Click OK
Scan your C Drive (Or your current system drive) and click OK. The scan will begin. This my take a moment, so please be patient. When the scan completes, click Save Report.
Name the log RootRepeal.txt and save it to your Documents folder - (Default folder).
Paste the log into your next reply.

Click RootRepeal.exe to open the scanner.



Hi rigel,

Thanks for this help. I'm having a problem installing RootRepeal. When I click on the .exe file I get some warnings from ZoneAlarm (but I authorize everything) and then the following error:

Could not find kernel file on disk (C:\WINDOWS\system32\ntoskrnl.exe)!

I can then do as you say, but the scan lasts less than a second and gives me a .dat file on the desktop.

Ok... we will revisit it after a Dr. web scan

Please download DrWeb-CureIt and save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)
Then please retry the rootrepeal scan. We need that tool to run correctly.

OK, great, thanks for this help. To respond to your first post, I have turned Teatimer off since installing MBAM paid version with protection module running.

I did as you said and ran Dr Web and here's what it came up with:

RegUBP2b-Anthony.reg;C:\Documents and Settings\All Users\Application Data\Spybot - Search & Destroy\Snapshots2;Trojan.StartPage.1505;Deleted.;
A0179636.dll;C:\System Volume Information\_restore{B37680B2-BA0A-4E5D-BF30-83E44C588624}\RP1838;Trojan.Virtumod.1666;Deleted.;

Then please retry the rootrepeal scan. We need that tool to run correctly.


I tried Rootrepeal again and the same error message appeared.

Thanks again for this help.

As always, thank you very much for your help. Before proceeding, I just want to make sure I understand the above quote from your instructions. Does this mean that when I re-boot in Safe Mode, I should log on as administrator, or is there simply an option when I run AFT-Cleaner to "Run as an Administrator?" Just want to be clear about this before proceeding.

Many thanks again.

OK, thanks again. My apologies, as well. When I printed out your instructions and read them more carefully (without kids running around), it was clearer that the information quoted concerned Windows Vista. I'm running XP Home. I did only run these utilities in my own account in Safe Mode (as I have done with each scan in safe mode since all of this began).

I ran the programs as asked and the good news is that nothing came back in the SuperAntiSpyware scan:

SUPERAntiSpyware Scan Log
http://www.superantispyware.com

Generated 05/17/2009 at 01:25 AM

Application Version : 4.26.1002

I did have a sluggish re-boot and a Windows "stop error" (but I was able to continue on with the re-boot no problem, so I'm not sure what got "stopped"). I chalk it up to the enormous amount of anti-spyware programs running: MBAM, ZoneAlarm Suite, SpywareBlaster and SuperAntiSpyware, which seems to be loading upon startup. Although I might be wrong....

The slow boot is probabily SuperAntiSpyware. You can uninstall it now.

Please update and rerun malwarebytes and post its fresh log. Thanks!

Let's flush your system restore ...

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 "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". 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 Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok"
  • Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" Tab.
  • 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 Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Please try RootRepeal again. Thanks
How are things running now?

OK, flushed the System Restore points.


Please try RootRepeal again. Thanks
How are things running now?


I tried to run RootRepeal again but the same Windows Kernel error appears. I actually played with it and I can get a scan and report if I click drivers, files, processes, and stealth objects. If I click either SSDT or Hidden Services (or both) in a scan, the scan fails. RootRepeal shuts down and I get a an empty .dat file on the desktop.

Otherwise, all seems to be running well. I never had any problems of sluggishness when starting this topic (that only occurred when I got infected at the beginning of the month, but all appeared to go away with various scans of SpyBot S&D and MBAM). When we finish working, I'd like your advice on what I should have up and running on my computer to try to avoid this kind of thing in the future (I know there's advice on this on this forum, but given the things you've helped me work through and the utilities, perhaps you'd have some suggestions based on what we've been using over the past few days).

Many thanks again.
