Jul 19, 2010
  1. Hello all,

    I recently found 2, sometimes more, iexplore.exe process running in my computer.
    Everytime I kill them, they star running again.
    This happens althought I use Google Chrome, rarely use IE8.
    From times to times I get a pop-up showed on, even thought I selectedm, in IE8, to block all pop-ups.

    I have avast 5 professional and Windows Defender.

    Any help please?

    Unfortunately, the hosting site has been down...

    Download Bootkit Remover to your Desktop.

    • You then need to extract the remover.exe file from the RAR using a program capable of extracing RAR compressed files. If you don't have an extraction program, you can use 7-Zip: http://www.7-zip.org/
    • After extracing remover.exe to your Desktop, double-click on remover.exe to run the program (Vista/7 users,right click on remover.exe and click Run As Administrator.
    • It will show a Black screen with some data on it.
    • Right click on the screen and click Select All.
    • Press CTRL+C
    • Open a Notepad and press CTRL+V
    • Post the output back here.

    You're very welcome :)
    You're infected with a rootkit, but we're not done.
    Usually, when there is one infection, there is more.
    We have to keep checking.

    Please download ComboFix from Here or Here to your Desktop.

    **Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved directly to your desktop**
    1. Please, never rename Combofix unless instructed.
    2. Close any open browsers.
    3. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.
      • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause "unpredictable results".
      • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.
      NOTE1. If Combofix asks you to install Recovery Console, please allow it.
      NOTE 2. If Combofix asks you to update the program, always do so.
      • Close any open browsers.
      • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
      • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.
      • If there is no internet connection after running Combofix, then restart your computer to restore back your connection.
    4. Double click on combofix.exe & follow the prompts.
    5. When finished, it will produce a report for you.
    6. Please post the "C:\ComboFix.txt"
    **Note: Do not mouseclick combofix's window while it's running. That may cause it to stall**

    Make sure, you re-enable your security programs, when you're done with Combofix.

    DO NOT make any other changes to your computer (like installing programs, using other cleaning tools, etc.), until it's officially declared clean!!!

    I strongly suggest, you uninstall RegCure. Registry tools are not recommended and here is why: http://miekiemoes.blogspot.com/2008/02/registry-cleaners-and-system-tweaking_13.html

    Open Windows Explorer. Go Tools>Folder Options>View tab, put a checkmark next to Show hidden files, and folders.
    Upload following files to http://www.virustotal.com/ for security check:
    - d:\windows\system32\mshtml.dll
    - d:\windows\explorer.exe
    IMPORTANT! If the file is listed as already analyzed, click on Reanalyse file now button.
    Post scan results.

    Good. Files are clean :)

    Uninstall Combofix:
    Go Start > Run [Vista users, go Start>"Start search"]
    Type in:
    Combofix /Uninstall
    Note the space between the "Combofix" and the "/Uninstall"
    Click OK (Vista users - press Enter).
    Restart computer.

    =====================================================================

    Download OTL to your Desktop.

    * Double click on the icon to run it. Make sure all other windows are closed and to let it run uninterrupted.
    * Under the Custom Scan box paste this in:



    netsvcs
    drivers32 /all
    %SYSTEMDRIVE%\*.*
    %systemroot%\system32\Spool\prtprocs\w32x86\*.dll
    %systemroot%\system32\*.wt

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install|LastSuccessTime /rs



    * 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.
    • Please copy (Edit->Select All, Edit->Copy) the contents of these files, one at a time, and post them back here.

    If you still have any tools or logs leftover on your computer you can go ahead and delete those off of your computer now.

    2. Right-click the My Computer icon, and then click Properties.
    3. Click the System Restore tab.
    4. Check "Turn off System Restore".

    2. Right-click the Computer icon, and then click Properties.
    3. Click on System Protection under the Tasks column on the left side
    4. Click on Continue on the "User Account Control" window that pops up
    5. Under the System Protection tab, find Available Disks
    6. Uncheck the box for any drive you wish to disable system restore on (in most cases, drive "C:")
    7. When turning off System Restore, the existing restore points will be deleted. Click "Turn System Restore Off" on the popup window to do this.
    8. Click OK

    2. Restart computer.

    3. Turn System Restore on.

    4. Make sure, Windows Updates are current.

    5. If any Trojan was listed among your infection(s), make sure, you change all of your on-line important passwords (bank account(s), secured web sites, etc.) immediately!

    6. Download, and install WOT (Web OF Trust): http://www.mywot.com/. It'll warn you (in most cases) about dangerous web sites.

    7. Run defrag at your convenience.

    8. Read How did I get infected?, With steps so it does not happen again!: http://www.bleepingcomputer.com/forums/topic2520.html
