I found a similar post to the problem I am having form a year ago here: http://www.bleepingcomputer.com/forums/t/168551/registry-defender-many-other-popups/

I was recently infected with a host of malware and have used Spyware Doctor, AVG 8.0, avast! 4.0, and Spybot Search & Destroy to manage to fix most of the problems.

However, I am still experiencing slowdowns in Firefox and many pop-ups (usually advertising registry defender). These pop-ups are opened independently by Internet Explorer under the guise of Firefox pop-ups. They have the firefox logo and windows task manager does not recognize Internet Explorer as running, but when I stop the iexplorer.exe process the windows close. I have not clicked on this pop-up.

Spybot Search & Destroy repeatedly reports the same security and firewall breaches despite multiple fixes. Suddenly, I was unable to open the task manager. I receive an error saying an administrator has disabled task manager. I unplugged and disabled my internet at this point. Shortly after all of my system tray icons vanished and my computer shut down. I can not reboot in safe mode. I get a blue screen stating "A problem has been detected and Windows has been shut down to prevent damage to our computer...." At the bottom it says "Technical Information: *** STOP: 0x0000007B (0xBACBF51C, 0XC0000034, 0x00000000, 0x00000000).

When I reboot not in safe mod I get a command prompt and an error message saying:
16 bit MS-DOS subsystem
E:\WINDOWS\system32\command.com
E:\PROGRA~1\Symantec\S32EVNT1.DLL. An installable Virtual Device Driver failed Dll initialization. Choose 'Close' to terminate the application.

Clicking close or ignore results in more of the same command prompts and errors popping up.

What should I do? Please help. I am using a separate computer to post this because I am afraid of connecting my primary computer with the virus/malware to the internet.

As no logs have been posted, I am shifting this topic from the specialized HiJack This forum to the Am I Infected forum.

==>PLEASE DO NOT NOW POST LOGS<== unless a log is specifically requested.
Help us help you. If HelpBot replies, you MUST follow step 1 in its reply so we know you need help.

Hello have you run HJT or ComboFix from that post?

Here's what we do first in normal mode ...


Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.

alternate download link

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.


Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

SUPERAntiSypware has a built in "Repairs" feature to fix policy restrictions and certain Windows settings which are sometimes targeted by malware infection. To use this feature, launch SUPERAntiSypware.

  • Click the Repairs tab.
  • Click on (highlight) "Repair broken SafeBoot key" and then click the Repair button.
  • You may be asked to reboot your computer for the changes to take effect.



Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.




Please ask any needed questions,post logs and Let us know how the PC is running now.

Thanks for the comprehensive instructions. I have a couple questions.

The main reason I have not posted any logs or run the recommended software yet is because I am afraid that my computer has a backdoor trojan and I'm afraid if I connect to the internet I may lose valuable information. So I have three questions about this:

Based on my description of the problem does it sound likely that I am vulnerable to attack and loss of precious information?

If I am indeed vulnerable to a backdoor trojan, can I fix it without wiping my hard drive or will I be permanently at risk?

Since I am worried about connecting to the internet, can I try the fix without running any updates or is it more important to make sure the program is fully updated?

Thank you again for all the assistance.

Ok we may quite possibly have a Rootkit and/or backdoor.. The symtoms appear that way. That said i will post this advice,I feel iy only too fair and you decide.
You can run these tools off Cd or a flash drive that you copy from a clean PC. Or we post you in the HJT forum but you will still have to work from Device to clean pC to post.

Rootkits, backdoor Trojans, Botnets, and IRC Bots are very dangerous because they compromise system integrity by making changes that allow it to by used by the attacker for malicious purposes. Rootkits are used by Trojans to conceal its presence (hide from view) in order to prevent detection of an attacker's software and make removal more difficult. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. They can disable your anti-virus and security tools to prevent detection and removal. Remote attackers use backdoors as a means of accessing and taking control of a computer that bypasses security mechanisms. This type of exploit allows them to steal sensitive information like passwords, personal and financial data which is send back to the hacker. To learn more about these types of infections, you can refer to:

What danger is presented by rootkits?
Rootkits and how to combat them
r00tkit Analysis: What Is A Rootkit

If your computer was used for online banking, has credit card information or other sensitive data on it, you should disconnect from the Internet until your system is cleaned. All passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised and change each password using a clean computer, not the infected one. If not, an attacker may get the new passwords and transaction information. If using a router, you need to reset it with a strong logon/password so the malware cannot gain control before connect again. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
What Should I Do If I've Become A Victim Of Identity Theft?
Identity Theft Victims Guide - What to do


Although the infection has been identified and may be removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume the computer is secure even if the malware appears to have been removed. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired so you can never be sure that you have completely removed a rootkit. The malware may leave so many remnants behind that security tools cannot find them. Tools that claim to be able to remove rootkits cannot guarantee that all traces of it will be removed. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

When should I re-format? How should I reinstall?
Help: I Got Hacked. Now What Do I Do?
Where to draw the line? When to recommend a format and reinstall?


Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. Some infections are difficult to remove completely because of their morphing characteristics which allows the malware to regenerate itself. Sometimes there is another hidden piece of malware which has not been detected by your security tools that protects malicious files and registry keys (which have been detected) so they cannot be permanently deleted. Disinfection will probably require the use of more powerful tools than we recommend in this forum. Before that can be done you will need you to create and post a DDS/HijackThis log for further investigation. Let me know how you wish to proceed.

I have decided to try fixing it for the time being. Thank you.

I downloaded the recommended files from your links following your instructions to the letter on a clean computer which runs Windows Vista and saved them from the desktop to a flash drive. I did not visit any other websites. As soon as I tried to eject the flash drive an error told me that the drive was still in use. When I tried again a blue screen came up on the computer with more information than I could not read (something about a file dump??) and soon restarted. Now the clean computer shows only a black screen and pointer that moves. Booting into safe mode shows that McAfee is completely disabled and my firewall is down.

What happened here? Are the links you gave me clean and safe?

Yes all the links are clean a nd tested.. It is this malware..
Try to run this.. Then malwarebytes in normal mode.
  • Download TDSSKiller and save it to your Desktop.
  • Extract its contents to your desktop and make sure TDSSKiller.exe (the contents of the zipped file) is on the Desktop itself, not within a folder on the desktop.
  • Go to Start > Run (Or you can hold down your Windows key and press R) and copy and paste the following into the text field. (make sure you include the quote marks) Then press OK.

    "%userprofile%\Desktop\TDSSKiller.exe" -l C:\TDSSKiller.txt -v

  • If it says "Hidden service detected" DO NOT type anything in. Just press Enter on your keyboard to not do anything to the file.
  • When it is done, a log file should be created on your C: drive called "TDSSKiller.txt" please copy and paste the contents of that file here.
I will be off until the morning now ... NYC

I ran Malwarebytes from the website you linked me to. I saved it as zztoy.exe and ran it.

Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.


I clicked OK to restart and my computer now shows the same screen I described initially (quoted below) for regular boot and safemode.

I get a blue screen stating "A problem has been detected and Windows has been shut down to prevent damage to our computer...." At the bottom it says "Technical Information: *** STOP: 0x0000007B (0xBACBF51C, 0XC0000034, 0x00000000, 0x00000000).
