This is a virus detection. Viruses are programs that self-replicate recursively, meaning that infected systems spread the virus to other systems, which then propagate the virus further. While many viruses contain a destructive payload, it's quite common for viruses to do nothing more than spread from one system to another.

Indication of Infection

  • Presence of any of the following files in the WINDOWS directory:
    • Desktop-shooting.exe
    • Hello-Kitty.exe
    • BigMac.exe
    • Cheese-Burger.exe
    • Blaargh.exe
  • Creation of additional files in the C:\Windows\Media folder as mentioned in the Characteristics section.
  • Attempts to ping the web addresses mentioned, on the 5th of the month
  • File deletion on the 7th of the month
  • Methods of Infection

    This worm attempts to use the KaZaa file-sharing network and MSN Messenger instant messaging network to spread. The worm cannot propagate without at least one of these applications being installed on the local system.

    When this worm is executed, it will modify the registry to instruct the Peer-to-peer (P2P) client KaZaa to use the %Windir%\Media folder as a shared location:

    • HKEY_CURRENT_USER\Software\Kazaa\LocalContent\


    I-Worm.Win32.Supova.49152 (Hauri), W32/Supova.E (F-Prot), Win32.Kitty.a (ESafe), Win32.Worm.Supova.C (AVX), WORM_SURNOVA.D (Trend)

    • Desktop-shooting.exe
    • Hello-Kitty.exe

    The worm executable uses an image of the Hello Kitty character for an icon:

    A text file is saved to the WINDOWS directory with a random 11-character name that reads:

    'Patch the leaks or the ship will sink'

    The worm also attempts to use MSN Messenger to send itself to users on the contact list. However, this functionality did not work properly during testing. The worm is designed to send one of the following messages to MSN Messenger users:

    • Hehe, check this out :-)
    • Funny, check it out
    • LOL!! See this :D
    • LOL!! Check this out :)
    • Hehe, this is fun :-)

    Next this virus deletes all files in these folders:

    • %WinDir%
    • %WinDir%\System
    • %WinDir%\System32
