For several weeks, I have been receiving emails telling me that my email
address is sending out virus-laden emails. In fact, my computer is not
sending them, but another computer infected with a virus, likely belonging
to a contester, is sending out emails and using email addresses from all
over that computer to 'spoof' many email addresses, including mine as the
"from" address. Many of the addresses I see being spoofed belong to other
contesters. Also, the subject lines of the messages include things like "VA
QSO PARTY" which tells me it has to be from a contester's computer.
Everyone should be running a virus protection program on their computers.
If you are not, you are likely to be infected already by one or more of
these email based viruses. Please, please obtain a virus scanner/monitor
program for your computer. There are many available and some are even free.
Part of the responsible way to run a "connected" computer is having virus
protection, and updating it frequently with the data that enables it to
continue to protect your computer. These updates are often called
"signature files".
In addition to running and properly maintaining a virus protection program,
a utility is available that can assist in detecting and repairing the
infection from the KLEZ virus(as well as some others).
The program is called "Kleztool.com" and you can download it from the
contesting.com website in the file libraries at this address:
http://www.contesting.com/libraries/Utilities
After you unzip the program, issue the following command at the dos window
prompt:
(Don't shut down Windows.)
KLEZTOOL /scanfiles
It will scan your entire hard drive and will report if it finds any infected
files.
Here's the technical stuff on what it does:

I-Worm.Sircam
-------------
If program find HKEY_LOCAL_MACHINE\Software\SirCam key in registry,
"@win \recycled\sirc32.exe" in autoexec.bat or \windows\run32.exe and
\windows\rundll32.exe was created on Delphi it:
delete registry keys

try to repair files
autoexec.bat
In case program can not delete or rename any files (it may be used at
that moment) it set these files to queue to delete or rename during bootup
process and offer user to reboot system.
I-Worm.Goner
------------
If gone.scr process exist in memory, program will try to stop it.
if file %Windows system directory%\gone.scr exist on hard drive,
program will try to delete it.
If program find %Windows system directory%\gone.scr key in
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run of system
registry, it will delete this key.

----------------------------------------------------------
If program find next processes in memory:
Krn132.exe
WQK.exe
or any processes, infected by I-Worm.Klez.e, I-Worm.Klez.f, I-Worm.Klez.h
and
I-Worm.Klez.a virus, it will stop them and delete their files from hard
drive
and links to their files from system registry.
If program find that WQK.DLL library has been loaded by any processes
it will rename file of this library and will remove it after system reboot.
In case program find such library in memory of your PC you should reboot
your
PC when program finish and start it the second time after reboot to clean
your
system registry.
If program find any infected processes in memory it will start scan of
your hard drive (and all mapped network drives if you specify /netscan in

I-Worm.Klez.h
and I-Worm.Klez.a infection.
If you specify /scanfiles key in command line program will scan your
hard drive (and all mapped network drives if you specify /netscan) in all
cases.
