    Hello,

    I've been attempting to clean up these trojans for days now but they keep respawning. I'm not sure what I'm missing. The two downloads I did when I first noticed the problem was downloading MSN Messenger and getting the new firefox update.

    I also found a copy of the csrss.exe file which was named csrss.ex_ in C:\Windows. I know this is not a valid file but am not sure if this has anything to do with the problems I listed before or if it's something else entirely. Thanks for any help!

    I am not seeing it in your logs....but if you have that file as C:\Windows\csrss.ex_ then it should be deleted as that is not the place for the legit file.

    I am not seeing anything in your logs. Are you still having problems?

    Actually it does seem to have gone away. I ran through the "Do this before posting" twice and that seems to have helped.

    Thanks so much for looking. I'm glad this is gone.

    Good..then lets do some 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.


    If you do get a success message, then it is time to do our final steps:


    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:
