Trojan Backdoor Virus

Attached is the OTL log. Dr Web indicates there were 13 files with errors. No threats detected. No infected, malicious, or suspicious items. No threats neutralized. Scan duration=2hrs & 32 mins. And yes; the problem still persists. Windows 7 MBR unreachable, so system has no option but to Boot from sector that root kit resides in. :frowning:

Bootmgr appears to be missing so we will see if we can find a spare

[*]Run OTL.
[*]Select All Users
[*]Under the Custom Scan box paste this in
netsvcs
%SYSTEMDRIVE%*.exe
/md5start
bootmgr.*
/md5stop
CREATERESTOREPOINT

[*]Click the Quick Scan button. Do not change any settings unless otherwise told to do so. The scan wont take long.
[*]When the scan completes, it will open two notepad windows. OTL.Txt and Extras.Txt. These are saved in the same location as OTL.
[*]Post both logs

THEN

Download aswMBR.exe ( 1.8mb ) to your desktop.
Double click the aswMBR.exe to run it Click the “Scan” button to start scan

On completion of the scan click save log, save it to your desktop and post in your next reply

Here you are sir. (I used an alias Windows 7 admin account) :slight_smile:
Perhaps I should have used “Stained”?

OK I have found a spare- lets try that shall we

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

Run OTL

[*]Under the Custom Scans/Fixes box at the bottom, paste in the following

:Files C:\bootmgr|C:\Windows\Boot\PCAT\bootmgr /replace

:Commands
[CREATERESTOREPOINT]
[Reboot]


[*]Then click the Run Fix button at the top
[*]Let the program run unhindered, reboot the PC when it is done
[*]Open OTL again and click the Quick Scan button. Post the log it produces in your next reply.

Here is the requested log. ???
Am I incorrect; does not OTL produce 2 results logs? Shouldn’t there be another called “Extras”??? If so, it failed to produce it. My apologies if I am incorrect here.
(P.S. I ran the scan 2 times.)

Well, the same old problems have returned in earnest (I was able to reinstall AVAST, but it cannot detect malware if it is hidden on an inaccessible section of the hard drive)(I ran a full system scan & boot scan & AVAST detected nothing.). At this point I am fairly certain that a root kit has created its own version of the MBR, is hidden, protected, and tricking the OS into loading from it, instead of the real MBR. I am contemplating the installation of Ubuntu OS to overwrite the hard drive, and then re-installing windows OS in the hope that this will overwrite the root kit code (In which ever boot sector it is residing.), and be rid of this problem (providing that it has not infected the BIOS as well). Or, somehow isolating the sector that the root kit is hiding in (Provided it can be located.) by creating a new boot partion with a real MBR, and positioning it so that the OS will boot from it instead(If this is feasible?). From what I have read online about the type of root kit/s I suspect to have infected my PCs, (TDL4, also known as TDSS, Alureon (Microsoft), Olmarik (ESET), or TidServ (Symantec), is a multi-component malware family used by botnet owners to steal information and generate revenue through ad clicks. Also see this link: http://www2.gmer.net/mbr/). they are extremely difficult to eradicate. These ideas may be unorthodox, impractical, or nonsensical, and yes I may be getting ahead of the process here, but sometimes it takes a bit of trickery to vanquish those nasty Trojans. What are your thoughts? ???

Try running all these 3 tools in safe mode[make sure u dont have a internet connection while running them] links below:

1.FixTDSS.
http://www.symantec.com/content/en/us/global/removal_tool/threat_writeups/FixTDSS.exe

2.Kaspersky virus removal tool.
http://www.kaspersky.com/antivirus-removal-tool?form=1

3.Bitdefender bootkit remover.

Hope this will fix it. :wink: just try it.

Greetins,
true indian :slight_smile:
I will run the tools as instructed and provide results. I am currently re-installing Vista OS. Be back soon.
Thank you!

Hello again,

Here are the results:

Kapersky tool result: no threats detected.
FixTDSS tool result: no threats detected.
Bitdefender tool error message: “Failed to intialize”. (Tried to run it in safe mode with networking)

Any suggestions on how to get Bitdefender tool to run? I tried sneaking it in via flash drive, and naming it family pics. Perhaps the root kit identified it and stop it from running.

try in safe mode without networking.

rename it randomly and then try it…if this doesnt work see page 3

Read the instructions, download and burn (maybe from another computer), finally use one of this rescue CD’s:

http://download.bitdefender.com/rescue_cd/

Here is a link for Bitdefender root kit removal tool for both 32bit & 64bit systems: http://www.malwarecity.com/blog/free-removal-tool-for-tdl4-available-now-1106.html

I was able to run Bitfender root kit removal tool on my 32bit system running vista, as well as my 64bit system; result “no threats detected” on either PC.

I was able to run FixTDSS result: Backdoor Tidserv has not been found on your computer.

I ran Kaspersky on 32bit system running Vista and attached the report. Odd items found.

did bitdefender tool run on the infected pc?

Reboot the computer and press F8 to get to the safe mode menu
Once there select recovery console
At the command prompt type :

FIXMBR

Accept the warning and then type Exit

tell me after this if same symtoms persist?

Recovery console is not one of the options on the “Advanced Boot Options” screen that appears after hitting F8.
The options are:
Safe Mode
Safe Mode with networking
Safe Mode with command prompt (Would this work?)
Enable Boot Logging
Last Known Good Configuration
Debugging Mode
Disable automatic restart on system failure
Disable Driver Signature Enforcement
Start Windows Normally

I thought the only way to access the Recovery Counsel was by Booting up OS installation disk, and selecting “Repair your Computer”. I am not trying to be flippant. I am just a little confused?

Boot from your windows installation CD,

When you reboot you will be presentes with a welcome screen . Click repair my computer

Select your operating system

Select Command prompt

At the command prompt type the following :

Bootrec.exe /FixMbr

Check out this link:
http://www.besttechie.net/forums/topic/12840-vistas-system-recovery-console/

try the above as i mentioned…

I did as instructed and this is the resulting error message: “FIXMBR” is not recognized as an internal or external command, operable program or batch file.

In Vista System Recovery Options I executed the command “Bcdedit” and I copied (By typing exactly what appears on the screen into notepad) and attached the result. Would please look at it?
I wondering if you were to look at yours and compare mine, if one could see an error, corruption, or root kit? Please be so kind as to check this out.
One item after “resumeobject” looks suspicious. I am going to compare my 2 PCs Windows Boot Manager settings. It would be most helpful to have other eyes on this. From this command window one can make major changes to the MBR. If you check the link in my last post, it lists commands.
You might find them intriguing.
Thank you so very much for your patience with me and all you are doing to help me with this!!!

[b]At the command prompt type the following :

Bootrec.exe /FixMbr [/b]

did u notice the space between .exe and /

I have tried as instructed via the command prompt but still get the same error message. Are you perhaps running an earlier version of Vista? See below:

The Recovery Console in earlier versions of Windows has been removed in this version of Windows and replaced by several tools located in the System Recovery Options menu. The System Recovery Options menu is on the Windows Vista installation disc. If your computer manufacturer has preinstalled recovery options, the menu might also be installed on your hard disk. If your computer does not include the System Recovery Options menu, your computer manufacturer might have customized or replaced the tool. Check the information that came with your computer or go to the manufacturer’s website.

If Windows doesn’t start correctly, you can use these tools to repair startup problems, restore your system files to an earlier point in time, run tests on your computer’s random access memory, and in some editions of Windows Vista, restore your entire computer and system files from backups. For more information, see What are the system recovery options in Windows Vista?

I am currently in Windows Vista Boot Configuration Data Store Editor via the command bcdedit /?. I checked a Microsoft technical support site for more information on commands in this particular environment. I found this command “bcdedit /?” is the “Help” command that lists a multitude of options for MBR configuration. I am going to see what I can find out by using the Commands that control the boot manager.
