Hi guys, I've been tackling this problem for many hours with little success. What happens is every time I open IE, a second, hidden, iexplore.exe runs. When I stop this hidden process, the visible IE window closes too. I have run Process Explorer and tried to end it, but it simply comes right back. There was an executable that may have been associated with this that appeared in the task manager. It was called 3Y0bmNgr.exe (or something close to that). I located it in C:\Windows\system32 and deleted it and it hasn't returned. Hope you can help!

Using Spyware Doctor, I detected several adware, malware and viruses including Virtumonde and Vundo. I also ran Malwarebytes and Spybot to help identify and remove each infection. I was finally able to get all of these spyware removal tools to show no infections. However, this problem with IE's hidden process still remains. These are the programs that I ran and allowed to remove any infections:
  • Spyware Doctor
  • Spybot Search & Destroy
  • HijackThis
  • Malwarebytes' Anti-Malware
  • Combofix
  • Ad-Aware
  • Vundofix
  • FixVundo
  • CCleaner
  • VirtumundoBeGone
  • Windows Defender
It appeared that a virus had created system restore points, and so I disabled System Restore and had that folder wiped out. Using Spyware Doctor, I deleted any infected registry keys and files.

So, according to all of the scans, the computer is clean...but I am very leary of this hidden IE process. It does not appear to inhibit IE, except that it takes a little while to open IE in the first place. It hesitates to go to the start page...I assume because this hidden IE is setting up something...wicked! =)

I am at a dead end here and need your help! Thanks!

Pentium 4 2.4 GHz

Hey there and welcome to BC. Lets see if your comp is really clean. Do the following and post the logs after you have done all three.

Malwarebytes Anti-Malware
  • Update Malwarebytes' Anti-Malware
  • Launch Malwarebytes' Anti-Malware
  • 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 or 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. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.[/list]
Also run


ATF
Please download ATF Cleaner by Atribune & save it to your desktop.
  • 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".
------------------------------------

SAS,may take a long time to scan
Please download and scan with SUPERAntiSpyware Free
  • If you cannot download from the link above, please download it here: Super AntiSpyware
    [list]
  • 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.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.
  • In the Main Menu, 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):[list]
  • 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".
Scan with SUPERAntiSpyware as follows:
  • 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".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • 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.[list]
  • 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.
Now post your logs for each one.
This will help us determine if your comp is really clean. The slowness might be caused by the use of ComboFix (although I am not too sure about that) CF is an extremely powerful tool and should only be used under the supervision of someone that knows its exact procedure and usage. (Not saying you dont).

You appear to be clean of malware, which is good.
Do you have another browser (i.e. Firefox, Opera, etc...)? If so open one of those and tell me if it starts two processes or just one?

Hey I just want to add that Spyware Doctor ran an Intelli-Scan in the background and detected 4 new infections. This is after I had everything cleaned. This hidden process must be pulling in more junk. I am using the free version so I will have to clean them manually, but I'll wait for your instructions before doing anything else. It detected the following:

Adware.Advertising
Application.TrackingCookies
Application.NirCmd
Trojan.Generic

Actually I should have asked this before, are you using IE8?
If you are, two processes are normal, one process is due to the actual IE, and then for each tab opened is another process. So when you start IE, it will have two processes. Please let me know and then we will complete your removal process.

Oh, wow. Yes, I am using IE8. I'm happy to hear it's so simple!!

Also, I'm curious as to how it could have been reinfected so quickly, when I did not (I don't believe) expose it to web sites with malware/spyware/etc. ?

Yes I know, its very possible you still have a trojan downloader that is reinfecting your comp. Could you run the ESET online scan as well as another MBAM quick scan and post your logs?
