    Unable to download HijackThis or other programs
    « on: September 12, 2008, 11:57:52 PM »
    After reading through the "Read this before requesting malware removal help" topic I tried to complete the steps, but was mostly unsuccessful.

    Step 1: I didn't find any suspicious programs.
    Step 2: CCleaner was already installed on my computer and I successfully ran the cleaner.
    Step 3: I received an "unable to connect" message when trying to install SUPERAntiSpyware.
    Step 4: I received an "unable to connect" message when trying to install MBAM using either link.
    Step 5: I installed the latest version of java and was able to remove the older versions.
    Step 6: I received an "unable to connect" message when trying to install HijackThis.

    When I recently tried to download a newer version of Windows Media Player my I got the same "unable to connect message when using mozilla firefox and internet explorer.  Another problem is when I search Google and click on the links they redirect me to another search engine.  I am still clinging to hope for my computer, please let me know if there is anything I can do to even start fixing this!  Thank-you.

    Welcome to CH.

    Download ComboFix by sUBs from one of the below links. Be sure top save it to the Desktop.

    Go here to download it. I just uploaded the new copy.

    http://www.filedropper.com/combofix_2

    **Note:  It is important that it is saved directly to your Desktop

    Close any open Web browsers. (Firefox, Internet Explorer, etc) before starting ComboFix.

    Temporarily disable your antivirus, and any antispyware real time protection before performing a scan. Click this link to see a list of security programs that should be disabled and how to disable them.
     
    Double click combofix.exe & follow the prompts.
    When finished ComboFix will produce a log for you.
    Post the ComboFix log and a new HijackThis log in your next reply.

    Important: Do not mouseclick ComboFix's window while it is running. That may cause it to stall.

    Remember to re-enable your antivirus and antispyware protection when ComboFix is complete.

      Note: the below instructions were created specifically for this user. If you are not this user, DO NOT follow these directions as they could damage the workings of your system

      Delete these files/folders, as follows:

      1. Go to Start > Run > type Notepad.exe and click OK to open Notepad.
      It must be Notepad, not Wordpad.
      2. Copy the text in the below code box by highlighting all the text and pressing Ctrl+C

      Code: [Select]
      KillAll::

      File::
      C:\WINDOWS\msdownld.tmp
      C:\WINDOWS\system32\1cHJkG4O.exe.a_a

      3. Go to the Notepad window and click Edit > Paste
      4. Then click File > Save
      5. Name the file CFScript.txt - Save the file to your Desktop
      6. Then drag the CFScript (hold the left mouse button while dragging the file) and drop it (release the left mouse button) into ComboFix.exe as you see in the screenshot below. Important: Perform this instruction carefully!



      ComboFix will begin to execute, just follow the prompts.
      After reboot (in case it asks to reboot), it will produce a log for you.
      Post that log (Combofix.txt) in your next reply.

      Note: Do not mouseclick ComboFix's window while it is running. That may cause your system to freeze

      Download SDFix by AndyManchesta and save it to your desktop. http://www.filedropper.com/sdfix_3

      When using this tool, you must use the Administrator's account or an account with Administrative rights

      • Double click SDFix.exe and it will extract the files to %systemdrive%
      • (this is the drive that contains the Windows Directory, typically C:\SDFix).
      • DO NOT use it 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".

      Open the SDFix folder and double click RunThis.bat to start the script.
      • Type Y to begin the cleanup process.
      • It will remove any Trojan Services or Registry Entries found then prompt you to press any key to Reboot.
      • Press any Key and it will restart the PC.
      • When the PC restarts, the Fixtool will run again and complete the removal process then display Finished, press any key to end the script and load your desktop icons.
      • Once the desktop icons load the SDFix report will open on screen and also save into the SDFix folder as Report.txt.
      • Copy and paste the contents of the results file Report.txt in your next reply along with a new HijackThis log.

        Sorry it took so long for me to reply, and thank-you for all your help so far!  My computer is already seeing results!  I have attached the combofix log, but I was unable to download the other program.  When I clicked on the link it took me to the homepage.

          • Double-click mbam-setup.exe and follow the prompts to install the program.
          • At the end, be sure a checkmark is placed next to the following:
            • Update Malwarebytes' Anti-Malware
            • Launch Malwarebytes' Anti-Malware
            • Then click Finish.
            • If an update is found, it will download and install the latest version.
            • Once the program has loaded, select Perform quick scan, then click Scan.
            • When the scan is complete, click OK, then Show Results to view the results.
            • Be sure that everything is checked, and click Remove Selected.
            • When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
            • The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
            • Copy and Paste the entire report in your next reply.
            Extra Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts, click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.

            ----------

            • Click on the Install button.
            • It will automatically place HJT in C:\Program Files\TrendMicro\HijackThis\HijackThis.exe.
            • Upon install, HijackThis should open for you.
            • Click on the Do a system scan and save a log file button
            • HijackThis will scan and then a log will open in notepad.
            • Copy and then paste the entire contents of the log in your post.
            • Do not have HijackThis fix anything yet. Most of what it finds will be harmless or even required.

              Looks good. How is everything now?

              Open HijackThis sna place a check mark next to:

              O23 - Service: McAfee Application Installer Cleanup (0003011221201853) (0003011221201853mcinstcleanup) - Unknown owner - C:\WINDOWS\TEMP\000301~1.EXE (file missing)

              Then click Fix checked.

                Download OTCleanIt.exe and save it to your Desktop.

                • Click the CleanUp! button.
                • Select Yes when the "Begin cleanup Process?" prompt appears.

                • The tool will delete itself once it finishes, if not delete it yourself.
                .

                Set a New Restore Point to prevent possible reinfection from an old one
                Setting a new restore point AFTER cleaning your system will enable your computer to roll-back to a clean working state if needed.
                • 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 Restore Point a name then click Create.
                • The new restore 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.
                • Next 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 clean one.
                You can find instructions on how to enable and re-enable system restore here:

                Windows XP System Restore Guide or Windows Vista System Restore Guide
                .
                ----------

                • Click Start Now
                • Check the box next to Enable thorough system inspection.
                • Click Start
                • Allow the scan to finish and scroll down to see if any updates are needed.
