Please follow the instructions for removing worms.

Windows NT/2000/XP/2003

In Windows NT/2000/XP/2003 you will also need to edit the following registry entries. The removal of these entries 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\
eth0 driver = exec.exe

and delete it if it exists.

Each user has a registry area named HKEY_USERS\[code number indicating user]\. For each user locate the entry:

HKU\[code number]\Software\Microsoft\Windows\CurrentVersion\RunOnce\
eth0 driver = exec.exe

and delete it if it exists.

Close the registry editor and reboot your computer.

W32/Spybot-Z is a peer-to-peer worm and a backdoor Trojan that copies itself into the Windows system folder with the name exec.exe or with a random name and sets the following registry entries:

HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce\
eth0 driver = exec.exe

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\
eth0 driver = exec.exe

The worm creates the folder <System>\kazaabackupfiles and copies itself into this folder as:
crack.exe
divx.exe
gg.exe
ich.exe
ie.exe
irc.exe
justin.exe
mp3.exe
pamela.exe
sex.exe
winamp.exe
xxx.exe

The worm also sets the following registry entry to point to this folder:
HKCU\Software\Kazaa\LocalContent\Dir0

W32/Spybot-Z terminates certain utility programs and logs on to a predefined IRC server and waits for backdoor commands.
