    Im running windows xp on an hp home computer and everytime I connect onto the internet AVG is finding a trojan horse.
    It says C:/winsok.exe Trojan horse Dropper.Agent.CSB
    So it gives me the option to heal or move to vault and I push heal,and it says it healed.
    But it comes back again.

    Any help?? Not sure what to do.

    In the Full Path of File to Delete box, copy and paste each of the following
    lines one at a time then click on the button that has the red circle with the
    X in the middle after you enter each file. It will ask for confirmation to
    delete the file. Click Yes. Continue with that same procedure until you have
    copied and pasted all of these in the Paste Full Path of File to Delete box.



    Note: It is possible that Killbox will tell you that one or more files do not
    exist. If that happens, just continue on with all the files. Be sure you
    don't miss any.

    Run AVG Anti-Spyware!

    # IMPORTANT: Do not open any other windows or programs while AVG is scanning as it may interfere with the scanning process:
    # Launch AVG Anti-spyware by double-clicking the icon on your desktop.
    # Select the "Scanner" icon at the top and then the "Scan" tab then click on "Complete System Scan".
    # AVG will now begin the scanning process. Be patient this may take a little time.
    Once the scan is complete do the following:
    # If you have any infections you will prompted, then select "Apply all actions"
    # Next select the "Reports" icon at the top.
    # Select the "Save report as" button in the lower left hand of the screen and save it to a text file on your system (make sure to remember where you saved that file, this is important).
    # Close AVG and reboot your system back into Normal Mode.



    reboot to normal mode and run a few online scans!



    Note: this is a stand alone, it doesn't install to start/programmes.

    Download Mwav,

    http://www.spywareinfo.dk/download/mwav.exe


    double click on it and it will extract to C:\kaspersky. Click
    on the kaspersky folder and click on Kavupd, a black dos window will open
    and it will update the programme for you, be patient it will take 5-10
    minutes to download the new definitions. Once it's updated, click on mwavscan
    to launch the programme.

    Use the defaults of:

    Memory
    startup folders
    Registry
    system folders
    services

    Choose drive , all drives and, click scan all files
    and then click scan/clean. After it finishes scanning and cleaning post
    the log here with a new hijack this log.

    Note: this is a very thorough scanner, it might take anything up to an hour
    or more, depending on how many drives you have and how badly infected your
    pc is.



    Highlight the portion of the scan that lists infected items and hold
    CTRL + C to Copy then paste it here. The whole log with be extremely
    big so there is no way to copy the whole thing. I just need the
    infected items list.




    post another hijack this log, the AVG Anti-Spyware log and the Mwav scan log.
