Our family computer is possessed by something. The kids are home for winter break, and I am not sure what they did to get this virus. The OS is XP.

The AVG can't update. I can't system restore (it can pick a restore button, but nothing happens when I push next). The computer has blue screened a few times (with the message that driver irql not less than or equal). And, when I try to go to sites on the internet, pages with ads pop up. If I try to go to this site or other sites that could help, it says internet explorer cannot display the page. (I am sending this from my laptop). Sites like msn.com come up fine.

I have no idea how to get started...

Hi and welcome to BC!

Try to download Malwarebytes and its updates to your computer. Rename the Malwarebytes file you downloaded to red.com Move the file to your infected computer via flash/pen drive and run it.

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • 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 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 and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

That did not go well. I was in the middle of running MBAM, when the computer blue-screened. When I tried to turn the computer back on, it got to the desktop, but the startup things didn't open. If I put the cursor on the start icon, it hourglasses. Nothing can be opened. Help!!!!!

Let's try safemode...

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". Once in safe mode, try running Malwarebytes. It isn't as strong there, but it may give us a foothold.

If that doesn't work let me know.

By the way, I was so frustrated with my computer in my last post, I forgot to thank you for your help!!!!

Oh, and my 12 year old just fessed up that there was a pop up that exploded into pop-ups when he was trying to find Simpsons' episodes on the internet yesterday.

You are welcome :thumbsup:, but now I have some bad news...

C:\WINDOWS\system32\TDSSoiqt.dll (Rootkit.Agent)

This is a part of the TDSS rootkit. I need to warn you about its possible effects.

IMPORTANT NOTE: One or more of the identified infections was related to a rootkit component. Rootkits and backdoor Trojan are very dangerous because they use advanced techniques (backdoors) as a means of accessing a computer system that bypasses security mechanisms and steal sensitive information which they send back to the hacker. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. Remote attackers use backdoor Trojans and rootkits as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge.

If your computer was used for online banking, has credit card information or other sensitive data on it, 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. They should be changed by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. 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?

Although the rootkit was identified and 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 that because the rootkit has been removed the computer is now secure. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. 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.

We can try to clean your system, but we would need to refer you to the HJT forums for the best chance of a cleaning. Let me know how you wish to proceed.

Well that sure is bad news. I would rather not reformat, but I guess it is kind of hard for me to assess the risk and make a good decision. The infected computer is used mostly by my kids, so no online banking. My son has e-mail and IM on it, so I logged on from my computer and changed his passwords for those. There might be a word document on the computer with confidential info. Would that info possibly be compromised too?

I don't think I would feel comfortable doing a reformat myself, so I would need to hire someone to back up all the data, reformat and reload the data... Only to have the risk that my kids could get the computer infected anew.

What would you do? I am asking you because I think you can better assess the risk I am facing (seems like a bit of an unknown to me).

Since you don't use the computer for any financial transactions, and it seems to be used by your son for basic messaging and email, we can try a clean here. One thing to note: that team is very busy and behind on logs, so patience will be needed.

Please follow this guide from step (6). Post a HJT log to the HJT forum and a Team member will be along to help you as soon as possible. You may wish to post a link back to this topic to see what was discussed thus far.

If you need any help with the guide, please let me know. Best wishes - you are in good hands...

Thanks again for your help.

Can the computer be used in the meantime or should we not use it until we finish all "cleaning"? Right now, the computer is turned off, until I know if it is safe to use. Not having use of the computer will make it a bit challenging for the kids to get their homework done (and school resumes tomorrow).

Also, would information in word documents have been compromised by the infections?

Probably not by that infection. Usually they are affected by the malware mix that comes after infection. Let them use it, but I wouldn't transfer any files / folders / term papers to another computer.

I am a bit confused by your response. Are you saying they shouldn't transfer documents (term papers, etc.) to another computer?

I would not move files to another computer until you can say everything is clean. If you are going to do, just be sure to scan them first. For instance - If your son were to take his term paper back to school to open on one of their computers, you should ask them to scan your flash drive first.
