    Thanks in advance for the great XP cleaning procedure

    I cleaned my son's viruses as best I could and still had a recuring threat detected with AVG resident shield.

    File name C:\windows\iexplore.exe
    Threat name Trojan horse downloader.BHO.S
    Details C:\windows\system32\cfmom.exe
    Process ID 588

    Windows XP SP3

    appears to be fixed
    let me know if I need to do any more

    Let's do this:

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

    Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

    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.

    Now use add/remove programs to uninstall:
    Java 2 Runtime Environment, SE v1.4.2_03"
    Java(TM) 6 Update 7

    Reboot and install:
    Java Runtime 6

    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.

    Be sure to tell me how things are running.

    Well this is interesting.....avenger reported that the files did not exist, yet they still show in your logs.

    Use windows explorer to find and delete (if found):
    C:\WINDOWS\ÿupd.dll
    C:\WINDOWS\ÿpt.html

    Let me know what you find.
