Please follow the instructions for removing worms.

Please read the instructions for removing worms.

Make a note of the names of the files you delete. You should delete any copies of Troj/Faith-A at the same time as you delete W32/Oror-A.

Windows NT/2000/XP

In Windows NT/2000/XP you will also need to edit the following registry key. The removal of this key is optional in Windows 95/98/Me.

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 key:

HKLM\Software\Microsoft\Windows\
CurrentVersion\Run\LoadCurrentProfile

and delete it if it exists.

There will also be another key in

HKLM\Software\Microsoft\Windows\CurrentVersion\Run

which points to one of the files that you removed. You should also delete this reference.

Close the registry editor.

Removal of other files

The worm creates the following text files which you may wish to delete.

C:\Windows\def12x.dll
C:\Windows\rn3a.vxd
C:\Windows\Winfile.dll
C:\shares.txt

The attached file has one of the following filenames:

Love Zodiak.exe
Sorry.exe
[TNT]!CC geN.exe
Osama Your Mamma.exe
Setup.exe
mTV Charts.exe
Blondies.exe
TNT!CC gEN.exe
Magic.exe
Love.exe
Zodiak.exe
mTV.exe
Faith.exe
Kama Sutra.exe
Fun.exe
Smile.exe
Pamela.exe
Candy.exe

When first executed the worm displays a fake error message that reads

"Your version of WinZip Self-Extractor is not licensed, or the license information is missing or corrupted. Please contact the program vendor or the web site (www.WinZip.com) for additional information."

The worm will attempt to copy itself to folders on local and shared drives using any of the following filenames:

Kama Sutra.exe
GiRlZ FoReVeR (Wow).exe
Nikita v1.1 (Zip).exe
Pamela Anderson (Porno Installation).exe
Britney Spears Naked.exe
Teen Sex Cam.exe
Kurnikova Screensaver (6+).exe
CrEdIt CaRdZ gEn.exe
SeX.eXe
Faith.exe.

The worm will always drop a copy of itself with the filename C:\Windows\Rundll16.exe and add the following registry entry so that Rundll16.exe is run when Windows starts up:

HKLM\Software\Microsoft\Windows\CurrentVersion\Run\LoadCurrentProfile

The worm randomly choses a single subfolder of the Program Files folder and places a copy of the worm in that subfolder. The filename of the new copy will be the name of the sub folder plus "16", "32", or "2K" e.g. Accessories2K.exe. An entry is added to registry key

HKLM\Software\Microsoft\Windows\CurrentVersion\Run

which points to the copy of the worm.

A file is randomly selected from the Windows system folder and a copy of the worm is created in the system folder with a filename constructed from the name of the randomly selected file plus "16, "32" or "2K". An entry is then added to the file win.ini so that this copy of the worm is run when Windows starts up.

If the title bar of a window contains any of the following strings then that window will be closed:

black
panda
shield
scan
mcafee
nai_vs_stat
virus
iomon
webcheck
mstask
navap
msie
agent
avp
alarm
zone
labs

The worm will delete files from folders whose names contain the words:

"zone" and "labs"
kaspers
mcafee
panda
avp
"pc" and "cillin"
"black" and "ice"
"norton" and "virus"

A large mIRC script will be created in the mIRC installation folder with the filename alias.ini, server.ini, notes.ini or popup.ini. This script is a mIRC backdoor Trojan and will be detected as Troj/Faith-A by Sophos Anti-Virus.

Finally the worm will send itself in an email to addresses retrieved from emails in the infected user's inbox.

The worm also creates the following non-viral text files:
C:\Windows\def12x.dll
C:\Windows\rn3a.vxd
C:\Windows\Winfile.dll
C:\shares.txt
