MSN worm variant still keeps updating  after “imageXX.zip“.

It may also called Win32.IRCBot.gen.

The worm will auto send a message to your friend with Attachment: “myphoto.zip” file,the message maybe will one of this:

  hey over there… check out my new photo!
  when youre around accept.. its my new default pic.

  holy shit this new pic is hot as fuck!
  I just made this design for a friend. U like it?
  I think I had sex with them :X What should i do?
  You don’t think I had sex with them… rite?
  Is it horrible if I only remember the sex?
  Is this really a pic of you?
  Would you have had a threesome with them?
  Wow! I can’t believe I had a threesome with them!
  You see these crazy people? Almost havin sex on the dance floor!
  u want to see something really funny? Take a look!
  I cant stop laughing!

  %Windows%\winload.log
 %System%\l32x.exe

The virus may also steal password information for e-gold and other data, then send this information to the hard-coded email address

The virus will auto run at Windows startup after modifying the registry as in this example -

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run\
load32 = C:\WINNT\System32\l32x.exe

The virus will load a second time as an accomplice to the Windows shell as in this example -

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\
Windows NT\CurrentVersion\Winlogon\
“Shell” = explorer.exe C:\WINNT\System32\vxd32v.exe
