    Hi,

    Unfortunately, I think my computer has been hit with 'Polynomial.Code.Exploit' malaware (at least from what I've trying to research online).

    The problem began yesterday and after downloading a .rar file from another forum and unpacking it, my Norton Antivirus Internet Security asked me if it was ok to allow a certain file to connect to the Internet. I didn't recognize it and blocked it for the moment. This would (and still is) contiuing to reoccur after constant Antivirus checks and the steps located here. (for instance, one of the files that attempt to connect to the Internet is TFeJ71tT.exe). Even after being deleted, they reappear.

    The logs are included below. Thank you for your time.

    Yup...that little booger does seem to want to come back.

    Turn off all anti-virus and anti-spyware while we do this, enable afterwards:

    download The Avenger by Swandog469, and save it to your Desktop.

    * Extract avenger.exe from the Zip file and save it to your desktop
    * Run avenger.exe by double-clicking on it.
    * Do not change any check box options!!
    * Copy everything in the Quote box below, and paste it into the Input script here: part of the window:

    * Now click the Execute button.
    * Click Yes to the prompt to confirm you want to execute.
    * Click Yes to the Reboot now? question that will appear when Avenger finishes running.
    * Your PC should reboot, if not, reboot it yourself.
    * A log file from Avenger will be produced at C:\avenger.txt and it will popup for you to view when you login after reboot.

    Also delete all files in the below folders except ones from the current date (Windows will not let you delete the files from the current day).
    C:\WINDOWS\Temp
    C:\Documents and Settings\%username%\Local Settings\Temp

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it. Then attach the new C:\MGlogs.zip file that will be created by running this and also attach the log from Avenger.

    Ooohh....what a sneak...yes there is something that is keeping it and changing the name...Now go to Bitscan link: agree to the license and then select Scan. DO NOT CHANGE THE OPTIONS TO SHOW ALL FILES SCANNED. That will make your logs huge and we don't need to see clean files. Once Bitdefender completes the scan:

    Click-on the Detected Problems tab. Then select Click here to export the scan report

    When the window comes up to save the report, change the Save as type: box to Text (Tab Delimited) (*.txt) and then in the File name box enter change to bdscan then click save. This will save a file named bdscan.txt in whatever folder you are currently in when you save the file (take notice of where you are at so you can find it later). This bdcan.txt file will actually contain HTML code that we can easily view later while reviewing your log. All we have to do is rename the file to bdscan.html.

    Hey TimW,

    I followed the instructions but when I had to save the report, the txt option was not available so I saved it as an html and then saved the html as a txt. I've attached both the txt and the html (in a Zip file). Please let me know if I should do it again or send the html file in another way. Thanks.

    Maybe we will get lucky this time. :)

    Sweet....any other issues?

    In the meantime, let's clean up:
    Copy the bold text below to notepad. Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.
    Make sure that you tell me if you receive a success message about adding the above
    to the registry. If you do not get a success message, it definitely did not work.

    Hey TimW. I completed the directions as followed and got a 'success' message and so far, everything is acting as normal. =D

    Thank you soooooo much! I can't express my gratitude enough to you and all your help.

    You are quite welcome.....here are the final instructions:


    1. We recommed you keep SUPERAntiSpyware and Malwarebytes Anti-Malware for scanning/removal of malware. Unless you purchase them, they provide no protection. They do not use any significan amount of resources ( except a little disk space ) until you run a scan.
    2. If we used Pocket Killbox during your cleanup, do the below

      * Run Pocket Killbox and select File, Cleanup, Delete All Backups
    3. If we had you use ComboFix, uninstall ComboFix (This uninstall will only work as written if you installed ComboFix on your Desktop like we requested.)
      • Click START then RUN and enter the below into the run box and then click OK. Note the quotes are required
      • "%userprofile%\Desktop\combofix" /u
        • Notes: The space between the combofix" and the /u, it must be there.
        • This will uninstall ComboFix and also reset hidden files and folders settings back to Windows defaults.
      • Delete the C:\combo-fix folder from combofix.

    4. If we had you run Avenger, you can delete all files related to Avenger now.
    5. If we had you run RenV.exe, you can delete it and the Log.txt file on your Desktop.
    6. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    7. If we had you download any registry patches like fixme.reg or fixWLK.reg (or any others), you can delete these files now.
    8. If running Vista, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
    9. Go to add/remove programs and uninstall HijackThis.
    10. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
    11. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning steps in the READ ME for your Window version and see the steps to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.

    12. After doing the above, you should work thru the below link:
