W32/Qizy-A

Please follow the instructions for disinfecting PE executables.

Windows NT/2000/XP/2003

In Windows NT/2000/XP/2003 you will also need to edit the following registry entry. The removal of this entry is optional in Windows 95/98/Me. Please read the warning about editing the registry.

At the taskbar, click Start|Run. Type 'Regedit' and press Return. The registry editor opens.

Before you edit the registry, you should make a backup. On the 'Registry' menu, click 'Export Registry File'. In the 'Export range' panel, click 'All', then save your registry as Backup.

Locate the HKEY_LOCAL_MACHINE entry:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run

and remove any reference to any file you deleted.

Close the registry editor.

W32/Qizy-A uses VBS/Qizy-A to mail itself to everyone in the Outlook address
book.

W32/Qizy-A attempts to prepend itself to any EXE files in the Windows folder,
the My Documents folder and the MIRC folder. Any RTX (ring-tone) files in the
My Documents folder are replaced with Jingle Bells. Another program,
C:\startup.exe, is dropped and the following registry entry is added so that
the new program is run on boot:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run

The dropped program informs the user of the infection and claims they may be
able to disinfect it once they answer ten questions correctly. The answers are:
reindeer, belgium, winter, cheese, companion, acx100, azerty, assembler, tcl,
spike.

On completing the quiz correctly, the user is advised to go to
www.geocities.com/quiz_map for disinfection instructions. The site contains a
map and five photos, allegedly giving directions to a 'package' which will
provide disinfection.
