    go to Moosoft.com and download the cleaner3.exe. It should detect and clean trojans on your computer. It also has realtime protection that moniters to see if a trojan is being installed

    Deleting the Files

    If your getting the "Access Denied" error that is probably because the files have registered themselves as services in Windows. Therefore, they are always in use and cannot be deleted while "in" Windows.

    To Delete Them:

    Try restarting in "MS-DOS Mode" and going to the directory they are located in and deleting them in DOS. After you are done deleting them type "win"

    How to Delete in Dos:

    (Just in case you don't know)

    del "file.ext" (remove the quotes)

    example: del test.txt

    Good Luck, I hope this helps

    If it's giving you an access denied error, then something probably has that file running. Try booting into safe mode and deleting the file that way. Only critical processes run in safe mode, so you should be able to delete them. If that doesn't work (and it should), boot into DOS and and try deleting them.

    Well, buddy... First of all you have to see what kind of files are running.. see it by pressing ctrl+alt+del... try to figure out what each one of them make and you will fix the problem.
    This doc can help you... read it and learn your own OS...

    All Known and Unknown Autostarting Methods used for executing files ( like trojans )

    1. Autostart folder
    Everything in here will restart.
    C:\windows\start menu\programs\startup {english}
    This Autostart Directory is saved in
    HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell
    Folders Startup="C:\windows\start menu\programs\startup"
    'So it could be easily changed by any program.

    2. Win.ini
    [windows]
    load=file.exe
    run=file.exe

    3. System.ini [boot]
    Shell=Explorer.exe trojanfile.exe

    4. c:\windows\winstart.bat
    'Note behaves like an usual BAT file. Used for copying deleting specific files. Autostarts
    everytime

    5. Registry
    [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices]
    [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce]
    [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run]
    [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce]
    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce]
    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunServices]

    6. c:\windows\wininit.ini
    'Often Used by Setup-Programs when the file exists it is run ONCE and then is deleted by
    windows
    Example: (content of wininit.ini)
    [Rename]
    NUL=c:\windows\picture.exe
    'This example sends c:\windows\picture.exe to NUL, which means that it is deleted. This
    requires no interactivity with the user and runs totaly stealth.

    7. Autoexec.bat
    Starts everytime at Dos Level.
    Example:
    Call C:\trojanfile.exe >nul
    Will run trojanfile.exe and redirect any output to nothing,
    so it will run totally stealth

    8. Registry Shell Spawning
    [HKEY_CLASSES_ROOT\exefile\shell\open\command] @="\"%1\" %*"
    [HKEY_CLASSES_ROOT\comfile\shell\open\command] @="\"%1\" %*"
    [HKEY_CLASSES_ROOT\batfile\shell\open\command] @="\"%1\" %*"
    [HKEY_CLASSES_ROOT\htafile\Shell\Open\Command] @="\"%1\" %*"
    [HKEY_CLASSES_ROOT\piffile\shell\open\command] @="\"%1\" %*"
    [HKEY_LOCAL_MACHINE\Software\CLASSES\batfile\shell\open\command] @="\"%1\" %*"
    [HKEY_LOCAL_MACHINE\Software\CLASSES\comfile\shell\open\command] @="\"%1\" %*"
    [HKEY_LOCAL_MACHINE\Software\CLASSES\exefile\shell\open\command] @="\"%1\" %*"
    [HKEY_LOCAL_MACHINE\Software\CLASSES\htafile\Shell\Open\Command] @="\"%1\" %*"
    [HKEY_LOCAL_MACHINE\Software\CLASSES\piffile\shell\open\command] @="\"%1\" %*"

    The key should have a value of Value "%1 %*", if this is changed to "server.exe %1 %*",
    the server.exe is executed EVERYTIME an exe/pif/com/bat/hta is executed.
    Known as Unkown Starting Method and is currently used by Subseven.

    9. Icq Inet
    [HKEY_CURRENT_USER\Software\Mirabilis\ICQ\Agent\Apps\test]
    "Path"="test.exe"
    "Startup"="c:\\test"
    "Parameters"=""
    "Enable"="Yes"

    [HKEY_CURRENT_USER\Software\Mirabilis\ICQ\Agent\Apps\
    This key includes all the APPS which are executed IF ICQNET Detects an Internet Connection.

    9. Misc Information
    [HKEY_LOCAL_MACHINE\Software\CLASSES\ShellScrap]
    @="Scrap object" "NeverShowExt"=""

    The NeverShowExt key has the function to HIDE the real extension of the file (here) SHS.
    This means if you rename a file as "Girl.jpg.shs" it displays as "Girl.jpg" in all programs
    including Explorer.
    Your registry should be full of NeverShowExt keys, simply delte the key to get the real
    extension to show up.

    10. Dosstart.pif
    Right click on it and go to properties. You can specify a custom autoexec.bat and
    config.sys when the computer is restarted in msdos mode.

    See you...

    Thumbs up

    what u can do is take the back up of all your important files and then format C drive and reinstall your operating system. this will refresh your registries and also clean all the trojans which might be present on your system.
    if u don't want to do this then go to tauscan there u can download the trojan scanner and fix your problem.

    Intruder, and what if the important files you're backing up, are infected?

    it doesn't matter if the files you backed up are infected bc when you restore they wont be running, they will be "dead" infections.
