Spyware.WinGuardian is a Windows-monitoring utility that runs stealthily and records all the activities.

This program logs what programs are run, text that is typed into the programs, Web sites visited, and captures screenshots.

When Spyware.WinGuardian is installed and run, it performs the following actions:
  1. Adds the value:

    "System"="C:\WINNT\system\sysctrl.exe /a"

    to the registry key:

    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

    so that the spyware is run every time that Windows starts.

  2. Adds the following subkey:

    HKEY_LOCAL_MACHINE\Software\CPNE

    and adds several registry values to this subkey.

  3. Creates the following files:
    • %SystemDrive%\Windows\System\system.in
    • %SystemDrive%\Windows\System\wglogs\system.lg
    • %SystemDrive%\Windows\System\wglogs\sc
    • %SystemDrive%\Windows\System\aup.in
    • %SystemDrive%\Windows\System\img.jpg
    • %SystemDrive%\Windows\System\message.in
    • %SystemDrive%\Windows\System\keyhook.dll
    • %SystemDrive%\Windows\System\sysctrl.exe
    • %SystemDrive%\Windows\System\chapinfo.txt
    • %SystemDrive%\Windows\System\unchap.drv
    • %SystemDrive%\Windows\System\sysfiles.in
    • %SystemDrive%\Windows\System\sys.exe
    • %SystemDrive%\Windows\System\sys.htm

      Note: %SystemDrive% is a variable that refers to the drive on which the Windows installation resides. By default, this is drive C.

  4. Runs stealthily in the background. To view the logs and change settings, you must use hot keys. The default hot keys are Ctrl+Alt+Shift+Y.

  5. Can be set to block specific Web sites.

  6. Send logs to an email address.
