Hi Technetters

Follow the instruction to remove the virus. Hopefully it will work.
Delighted to serve the technetters.


i)    In Windows 95 Explorer look for the files called SKA. If you do
not find them the virus is not there but I am sure it
is.

(ii)    In Windows 95 Click "Start" and then "Shut down", then click on
"Restart in MS DOS mode."

(iii)    On restart you can move around the system on standard DOS
commands.

        These are     cd windows  to move to windows
                            cd system     to move to system in windows
                            dir/p             to check the directory one
page at a time, pressing <enter> will display the next page
                            cd ..             to move back one directory

                            del <filename> to delete a named file, it
should have the name and extension
                            ren wsock32.ska wsock.dll       will rename
the file.

The following set of instructions were provided to me by a consultant
who had also been sent the virus in error and should
be read thoroughly before starting work on the deletion. They provide
the exact names of files and the sequence in which
to do it.


  The worm infects a system via email delivery and arrives as an
attachment  called Happy99.EXE. It is sent unknowingly by a user. When
the program is  run it deploys its payload displaying fireworks on the
users monitor. When  the Happy.EXE is run it copies itself to
Windows\System folder under the  name SKA.EXE. It then extracts, from
within itself, a DLL called SKA.DLL  into the Windows\System folder if
one does not already exist. Note: Though  the SKA.EXE file file is a
copy of the original it does not run as the  Happy.EXE files does, so it
does not copy itself again, nor does it display  the fireworks on the
users monitor. The worm then checks for the existence  of WSOCK32.SKA in
the Windows\System folder, if it does not exist and a the  file
WSOCK32.DLL does exist, it copies the SOCK32.DLL to WSOCK32.SKA.  The
patched code calls two exported functions in SKA.DLL called mail and
news, these functions allow the worm to attach itself to SMTP e-mail
and  also to any postings to newsgroups the user makes.

  To remove the virus worm do the following:- do the below in dos, not
in  windows 95/98, as in windows 95/98 uses the wsock32.dll file and
will not  let you delete the file.

  1. find and delete SKA.exe , liste.ska and SKA.dll
  2 delete wsock32.dll
  3 rename wsock32.ska to wsock32.dll Problem solved.
