  1. Hello all.

    My computer has been running slowly lately, and I am not sure of the cause. One of my first suspects is having malware on my computer, especially since my dad is not very experienced with computers and browses websites originating from China. Anyways, I followed the Viruses/Spyware/Malware Preliminary Removal Instructions.

    Problems encountered:
    - Online Scanner from Trend Micro.... was scanning, then half way in between it stopped working.
    - Panda Anti-Rootkit scan.... was performing in-depth scan, and when it reached 23% for the Registry Scan, the program encountered a problem and had to be closed. I tried it again twice, and the same result occured.

    Logs included.

    Thank you to all that will help in advance.

    Download Sophos Anti-Rootkit & save it to your desktop after filling out the questionaire and reading the EULA.

    Note: You will need to enter your name, e-mail address and location in order to access the download page.
    • Double-click sarsfx.exe to extract the files.
    • Click the Accept button at the EULA, then Install to the default directory
    • At the next prompt, click Yes to start the program
    • Make sure the following are checked:

      • [*]Running processes
        [*]Windows Registry
        [*]Local Hard Drives
    • Click the "Start Scan" button.
    • Allow the program to scan your computer - please be patient as it may take some time
    • Once the scan has completed a window will pop-up with the results of the scan - click OK to this
    • In the main window, you will see each of the entries found by the scan (if any)
      • If the scanner generated any warning messages, please click on each warning and copy and paste the text of it into this thread for me to review
      • Once you have posted any warning messages here, you can close the scanner and wait for me to get back to you
    • If you have not had any warnings, any entries which can be cleaned up by the scanner will have a box with a green checkmark in it next to the entry
    • To clean up these entries click on the Clean up checked items button
    • If you accidentally check a file NOT recommended for clean up, you will get a warning message and if necessary can re-select the entries you want to clean up
    • Once you have cleaned the selected files, you will be prompted to re-boot your computer - please do so
    • When you have re-booted, please post a fresh HijackThis log into this thread and tell me how your computer is running now

    I have scanned my computer using Sophos Anti-Rootkit.

    The registry value can not be checked, and the file is removable, but the program does not reconmmend removing it, so I did not remove it.

    The hidden file appears to be a part of Folder Lock program.

    However, the registry entry I would like to look deeper because this key is where the system stores entries representing approved user interface extensions - why is haaehmnbicfjdbkc an approved shell extension


    In notepad click Format and make sure "word wrap" is off or unchecked

    Open notepad and copy and paste next bold in it:

    [B]regedit /e peek.txt "HKEY_USERS\S-1-5-21-1004336348-1682526488-682003330-1006\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved\{99D00C5F-26F7-4611-6886-836D4DF719C7}"
    type peek.txt >> look.txt
    del peek*.txt
    start notepad look.txt[/B]
    Save this as look.bat , choose to save as *all files and place it on your desktop.

    It should look like this on your desktop: [​IMG]

    Doubleclick look.bat
    Notepad will open with some txt in it. Copy and paste the contents in your next reply.

    In addition to the above.

    Run Smitfraudfix
    • Download Smitfraudfix by S!ri from HERE
    • Double-click SmitfraudFix.exe
    • Select 1 and hit Enter
    • The report can be found at the root of the system drive, usually at C:\rapport.txt

    Let's try this a different way, as I don't like hex code -

    Open notepad and copy and paste next bold in it:

    [B]reg query "HKEY_USERS\S-1-5-21-1004336348-1682526488-682003330-1006\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved\{99D00C5F-26F7-4611-6886-836D4DF719C7}"  >> C:\look.txt[/B]
    Save this as look.bat , choose to save as *all files and place it on your desktop.

    It should look like this on your desktop: [​IMG]

    Doubleclick look.bat
    Notepad will open with some txt in it. Copy and paste the contents in your next reply.

    Didn't work... as in no look.txt
  9. Blind Dragon

    Blind Dragon TS Evangelist Posts: 3,908

    What about when you go to C:\look.txt

    Is the file there?
  10. ChrisLam

    ChrisLam TS Rookie Topic Starter Posts: 82

    Oh yea, but it's empty.

    Backup your regsitry
    First, we need to backup your registry:
    Please go to Start > Run
    Paste in the following line:
    • regedit /e c:\registrybackup.reg
    Click OK.
    It won't appear to be doing anything, that's normal.
    Your mouse pointer may turn to an hour glass for a minute.
    Please continue when it no longer has the hour glass.

    Making a .reg file
    Open notepad and copy and paste the text in the quotebox below in it:

    [HKEY_USERS\S-1-5-21-1004336348-1682526488-682003330-1006\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Approved\{99D00C5F-26F7-4611-6886-836D4DF719C7}]
    Name the file as Fix.reg

    Change the "Save As" type to "All Files" and save it on the desktop.

    It should look like this: [​IMG]

    Double-click on it and when it asks you if you want to merge the contents to the registry, click yes/ok.

    Currently, I am scanning using the Kaspersky Online AV Scanner.

    So far, the computer seems to be running faster, and the mouse no longer lags! Bootup time and login time is still slower than I remembered, however.

    Also, the other computer... with the missing explorer.exe... the problem seems fixed, but when I browse websites using Firefox, it tells me that the certifacates have expired... also, MSN does not log in. Is there something that could be intercepting our data being sent and received? I am thinking of reformatting... since my mom does banking on the computer. Any thoughts?

    Computer (the one with the hijackthis logs) is from September 2005
    Intel Celeron D330 @ 2.66 ghz
    Windows XP Pro
    80GB Samsung HHD
    512MB Kingston RAM
    Asus P4P800-MX
    Integrated everything

    Results of the Kaspersky Online Scanner in attachment.

    P.S. This scanner is a pain in the **** in my opinion.... first few times I tried to scan, it said that I had to go online to scan, then when it worked. I tried saving it to my desktop, but it wouldn't respond... I couldn't choose to save it as a text file too from the drop down menu (so I saved it in the filename as a .txt), and when I pressed save, nothing happened! I'm just glad it's over (for now at least :D)... The file appeared in My Documents :D.

    I know it is a pain, but it detects so many things it is a great 2nd opinion as to whether you are clean or not. And it didn't find anything so that is good news. As you can see though it even detected the infection in your old restore point and in quarantine, then gave a false positive on the smitfraud tool.


    Good work.

    Uninstall Combofix
    * Click START then RUN
    * Now type Combofix /u in the runbox
    * Make sure there's a space between Combofix and /u
    * Then hit Enter.

    * The above procedure will:
    * Delete the following:
    * ComboFix and its associated files and folders.
    * Reset the clock settings.
    * Hide file extensions, if required.
    * Hide System/Hidden files, if required.
    * Set a new, clean Restore Point.


    OTCleanit! by Oldtimer
    • Download OTCleanIt
    • Click the CleanUp! button.
      • It will go thorugh the list and remove all of the tools it finds and then delete itself (requiring a reboot).


    Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:
    1. Set correct settings for files
      • Click Start > My Computer > Tools menu (at top of page) > Folder Options > View tab.
      • Under "Hidden files and folders" if necessary select Do not show hidden files and folders.
      • If unchecked please check Hide protected operating system files (Recommended)
      • If necessary check "Display content of system folders"
      • If necessary Uncheck Hide file extensions for known file types.
      • Click OK

      clear system restore points

      • This is a good time to clear your existing system restore points and establish a new clean restore point:
        • Go to Start > All Programs > Accessories > System Tools > System Restore
        • Select Create a restore point, and Ok it.
        • Next, go to Start > Run and type in cleanmgr
        • Select the More options tab
        • Choose the option to clean up system restore and OK it.
        This will remove all restore points except the new one you just created.

    2. Make your Internet Explorer more secure - This can be done by following these simple instructions:
      1. From within Internet Explorer click on the Tools menu and then click on Options.
      2. Click once on the Security tab
      3. Click once on the Internet icon so it becomes highlighted.
      4. Click once on the Custom Level button.
        • Change the Download signed ActiveX controls to Prompt
        • Change the Download unsigned ActiveX controls to Disable
        • Change the Initialize and script ActiveX controls not marked as safe to Disable
        • Change the Installation of desktop items to Prompt
        • Change the Launching programs and files in an IFRAME to Prompt
        • Change the Navigate sub-frames across different domains to Prompt
        • When all these settings have been made, click on the OK button.
        • If it prompts you as to whether or not you want to save the settings, press the Yes button.
      5. Next press the Apply button and then the OK to exit the Internet Properties page.
    3. Use an AntiVirus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

      See this link for a listing of some online & their stand-alone antivirus programs:

      Virus, Spyware, and Malware Protection and Removal Resources

    4. Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

    5. Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

      For a tutorial on Firewalls and a listing of some available ones see the link below:

      Understanding and Using Firewalls

    6. Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.This is done in Vista through control panel -> windows updates.

    7. Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

      A tutorial on installing & using this product can be found here:

      Using SpywareBlaster to protect your computer from Spyware and Malware

    8. Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
    Follow this list and your potential for being infected again will reduce dramatically.

    here are some additional utilities that will enhance your safety

    • IE/Spyad <= IE/Spyad places over 4000 websites and domains in the IE Restricted list which will severely impair attempts to infect your system. It basically prevents any downloads (Cookies etc) from the sites listed, although you will still be able to connect to the sites.
    • MVPS Hosts file <= The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your coputer from connecting to those sites by redirecting them to which is your local computer
    • Google Toolbar <= Get the free google toolbar to help stop pop up windows.
    • Winpatrol <= Download and install the free version of Winpatrol. a tutorial for this product is located here:
      Using Winpatrol to protect your computer from malicious software
