My wife's computer is infected with a virus/spyware that puts a popup on the screen whenever she opens a new browser window or whenever something is loading on a webpage.

The title of the popup: Critical System Error!
Body of the popup: Your computer is infected with Trojan.Win32.obfuscated.gx
It's dangerous for your system, some files can be lost and your browser can be slow!
Click OK to download the antispyware program to clean your computer! (Recommended)

Then there are two buttons: [Ok] , [Cancel] :thumbsup:

She said that she has had this popup ever since she was asked (she doesn't recall how) to update the Divx player software.

She has installed:
Windows XP Pro SP2
IE version 6.0.29
AVG 7.5 trial antivirus software
Ad-Aware 2007 free version from lavasoft

we had spyware hunter installed until I learned that it has possible ties to adware/spyware and removed it (hopefully.)

Any help will be greatly appreciated. Thank You!!

Hello and Welcome to Bleeping Computer Thallian.
Please follow this BC Tutorial and tell how you do.

How to remove IE Defender (Removal Instructions)


Well, It's not IE Defender.. It is not in my Add/Remove Programs listing.

So far I have run these programs thus far:
AdAware
Vundo Fix

Right after typing this I am going to run VirtumundoBegone because Vundo Fix found nothing.

BTW - this popup looks authentic - like a Windows popup and doesn't show up on the taskbar at all. Any ideas would be greatly appreciated because this thing is driving me :thumbsup:

BTW - I was wrong - Vundo Fix did find a few things - but not the major one that I am having problems with.

VirtumundoBeGone seems to have found something else and gotten rid of it also - but I still have the popup...

Please... any ideas of what I should do next?? or what programs I can use next??

Download "FixIEDef.exe" by ShadowPuterDude and save it directly to your Desktop <- (Important!).
  • Double-click FixIEDef.zip which will create a folder named FixIEDef on your Desktop.
  • Double-click of the FixIEDef folder.
  • Locate FixIEDef.bat and double-click on it.
  • FixIEDef will now run.
  • Press any key to close the Command Console when the script is finished and Explorer has restarted.
Instructions with screen shots here if needed.

-- FixIEDef will kill all copies of Internet Explorer and Explorer that are running. The icons and Start Menu on your Desktop will not be visible while FixIEDef is running. This is necessary to remove parts of the infection that would otherwise not be removed. FixIEDef will re-start Explorer at the end of the removal process.

-- You will need to temporarily disable any programs you have running that will block attempts to edit the registry.


Note: Certain embedded files that are part of legitimate programs or specialized fix tools such as process.exe may at times be detected by some anti-virus/anti-malware scanners as a "RiskTool", "Hacking tool", "Potentially unwanted tool", or even "malware (virus/trojan)" when that is not the case. It is not a virus, but a program used to stop system processes. Antivirus programs cannot distinguish between "good" and "malicious" use of such programs, therefore they may alert the user.

Please download ATF Cleaner by Atribune & save it to your desktop. DO NOT use yet.
Please download and install SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.

  • Under the "Configuration and Preferences", click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and 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 a scan just 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".

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 browser click Firefox 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.
  • If you use Opera browser click Opera 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.
Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".

  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • 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.

Good job.

If there are no more problems or signs of infection, 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 "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".
  • Click the "More Options" Tab.
  • Click "Clean Up" in the System Restore section to remove all previous restore points except the newly created one.

Quietman7.

Thank You! Thank You! Thank You!

Her system is running great - we created the restore point and cleaned the others like suggested.

New Question:

I wanted to run through this gauntlet of programs on my machine just to make sure that I am totally clean also but whenever I try to goto Safemode my computer just shuts off (like I held in the power button for 4 seconds) - it turns completely off like I pulled the cord. :thumbsup: That has me a little worried. Do you think that I am infected or do I have a Win XP problem??

Any ideas?

Thanks.

Some types of malware can delete or alter the safeboot key in the registry resulting in the inability to reboot into safe mode.

Go to Start Run and type: regedit
  • Click OK.
  • On the left side, click to highlight My Computer at the top.
  • Go up to File Export
    • Make sure in that window there is a tick next to "All" under Export Branch.
      Leave the "Save As Type" as "Registration Files".
      Under "Filename" put RegBackup.
  • Choose to save it to C:\
  • Click save and then go to File Exit.
Download SafeBootKeyRepair.exe by sUBs and save to your desktop.
  • Double-click on it and follow the instructions.
  • When finished, reboot and see if you can access safe mode.

Welcome to BC turkd3000

You need to be careful about following specific instructions provided to someone else. Those instructions were given to help fix that particular member's problems, NOT YOURS. Before taking any action, we must investigate the nature of the malware issues and then formulate a fix for the victim. Although the problem may be similar, the solution could be different based on the kind of hardware, software, system requirements, etc. and the presence of other malware. Using someone else's fix instructions could lead to disastrous problems with your operating system. It's best that members start their own topic and you tell us what specific issues they are having rather than point to someone else. In this case, the above fix is already outdated but I'm glad it resolved your problem.
