Removing The Msn Virus

Instant messaging has been increasing for years. And most popular IM software is Msn messenger. As the use of Msn messenger increases, more worms and viruses get propagated through the messenger. Here’s the latest one usually called the Msn virus.

Technical Names:

Also known as W32.Mimbot.A, W32/Delf-EXR, WORM_IRCBOT.AJY

What it does:

It comes through Msn messenger as an attachment. Once executed, it creates the following files:

  • %Windir%\ (A zipped copy of the worm.)
  • %System%\prodigys323.dll
  • %Windir%\
  • %System%\newsystem25.dll

It then creates some of the following registry entries so that it runs every time Windows starts:
? HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{448BAC42-AABD-42C5-A550-826BF4AF4BB3}\InProcServer32\”(Default)” = “prodigys323.dll”
CurrentVersion\ShellServiceObjectDelayLoad\”prodigy1″ = “{448BAC42-AABD-42C5-A550-826BF4AF4BB3}”

? HKEY_CLASSES_ROOT\CLSID\[RANDOM CLSID]\InProcServer32\”(Default)” = “newsystem25.dll
The worm then opens a back door through an IRC server on the domain on TCP port 81 or through the IRC server on TCP port 81 and awaits further commands from a remote attacker that allow it to perform various actions, including downloading and executing remote files.
It then sends itself to all the Msn contacts available. You can read more detail about the worm here.
