    Hi all

    This is my first post here. I caught a virus with nasty components whilst helping people transfer photos. I think I nailed all instances of virus & malware but have a nagging hang-on that is sending me round in circles.

    I'm on XP Pro, if I go into folder options & adjust anything, a malicious script resets my setting to hide system files & file extensions. I can over ride this through reg edit but as soon as I touch folder options it happens again.

    I can not detect anything through scans, malware scanners & am looking for help. I'm happy to start at the begginning & go back through everything.

    Although I don't think there is any malicious software running it is a little inconvenient (& also intriguing)

    Thanks in advance

    Please begin by clicking Start > Control Panel > System > Hardware > Device Manager > View > Show Hidden Devices.
    • Scroll down to “Non-plug and Play Drivers” and click the plus icon to open those drivers.
    • Then search forTDSSserv.sys
    • Let me know if you find this or not.
    • If you do find it, right click on it, and select Disable. Do not try to uninstall it.
    • Also if TDSSserv.sys is found and you disable it, then reboot.
    • After reboot continue on with the below cleaning instructions.

    Please follow the instructions in the below link and attach the requested logs when you finish these instructions.

    • If something does not run, write down the info to explain to us later but keep on going.
    • Do not assume that because one step does not work that they all will not.
    Notes:
    1. If you run into problems trying to run theREAD & RUN ME or any of the scans in normal boot mode. You can run steps in safe boot mode but make sure you tell us what you did later when you post logs. See the below if you do not know how to boot in safe mode:
    2. If you have problems downloading on the problem PC, download the tools on another PC and burn to a CD. Then copy them to the problem PC. You will have to skip getting updates if (and only if) your internet connection does not work. Yes you could use a flash drive too but flash drives are writeable and infections can spread to them.

    Hi Corporal Punishment

    Thanks for the reply.

    No sign of TDSSserv.sys

    I had followed the instructions "READ & RUN ME FIRST. Malware Removal Guide" before posting on the forum. I couldn't find anything wrong, would you like me to post logs?

    Yes. That is what the instructions tell you that you should do if still having problems.;)

    Uninstall the below old versions of software:
    J2SE Runtime Environment 5.0 Update 4

    Now we need to use ComboFix to remove a bunch of malware files.
    • Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
      • If it is not on your Desktop, the below will not work.
    • Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
    • Open Notepad and copy/paste the text in the below quote box into it:
    • Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
    • At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
    • You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
    • Now use your mouse to drag CFscript.txt on top of ComboFix.exe
    • Follow the prompts.
    • When it finishes, a log will be produced named c:\combofix.txt
    • I will ask for this log below
    Note:

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


    After reboot, now install the current version of Sun Java from: Sun Java Runtime Environment
    Now run Ccleaner to clean out only temp files and nothing else!

    Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

    Then attach the below logs:
    • C:\ComboFix.txt
    • C:\MGlogs.zip
    Make sure you tell me how things are working now!

    You're welcome. Your logs are clean.


    If you are not having any other malware problems, it is time to do our final steps:
    1. We recommend 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 significant amount of resources ( except a little disk space ) until you run a scan.
    2. 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:\combofix folder from combofix (if it exists)
    3. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
    4. 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.
    5. Go to add/remove programs and uninstall HijackThis.
    6. You can delete the C:\MGtools folder and the C:\MGtools.exe file. You can also delete the C:\MGlogs.zip
    7. If you are running Vista, Windows XP or Windows ME, do the below:
      • Refer to the cleaning procedures in step 3 the READ ME for your Window version and see the instructions to Disable System Restore which will flush your Restore Points.
      • Then reboot and Enable System Restore to create a new clean Restore Point.
    8. After doing the above, you should work thru the below link:
