Installation

This worm drops the following non-malicious files:

  • Desktop_1.ini
  • Desktop_2.ini

It drops the following copies of itself depending on the platform/operating system of the affected computer:

HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Run
Explorer = %System%\drivers\Messages.exe

Other System Modifications

This worm deletes the following files:

  • %System%\drivers\etc\hosts

(Note: %System% is the Windows system folder, which is usually C:\Windows\System on Windows 98 and ME, C:\WINNT\System32 on Windows NT and 2000, or C:\Windows\System32 on Windows XP and Server 2003.)
